Abstract The addition of Lewis bases L to the methyl(methylidene)boranes MeB=CA 2 (A = SiMe 3 ) and MeB=CAA′ (A′ = SiMe 2 Cl) gives the adducts MeB(L)=CA 2 ( 1a , b ; L = trimethylpyridine, PMe 3 ) and MeB(L)=CAA′ ( 1c , d ; L = di‐ and trimethylpyridine), respectively. Alcohols and amines HX are added to the BC double bond to give boranes MeB(X)—CHA 2 ( 8a — c ; X = O i Pr, O t Bu, N i Pr 2 ); MeB=CAA′ and HNMe 2 react in the ratio 1:2, yielding MeB(X)—CHA(SiMe 2 X) ( 2d ; X = NMe 2 ). From MeB=CA 2 and BH 3 , the five‐membered ring [—CA 2 —BH— ...

Unusual skeletal substitution reactions (such as the example shown right) are characteristic of the reactivity of cyclic borataphosphazenes towards halide abstraction agents with counterions such as [BF4]−, [AsF6]−, and [SbF6]−. In other cases ([AlCl4]− and [GaCl4]−) stable borazine–phosphazene hybrid rings are formed.

One boron—chlorine bond perpendicular to the plane of the ring is significantly longer than the in-plane BCl bond—this is the surprising result of the X-ray structure analysis of the BNP heterocycle 1. The zwitterion 1 reacts with GaCl3 under halide abstraction to give 2, which possesses the first authentic hybrid borazine—phosphazene ring [Eq. (a)].

A 1.3‐Methyl Shift along the Unsaturated BCSi Skeleton The synthesis of the methoxy[tris(trimethylsilyl)methyl]boranes X‐(MeO)B–C(SiMe 3 ) 3 ( 1a‐d ; X = Cl, Br, Ph, PhCH2) is described. The methylenoboranes Me‐B=C(SiMe 2 Hal) ( 3a, b ), the 2,3‐dihydro‐1H‐1‐sila‐3‐boraindene species 6 , and the 1,2,3,4‐tetrahydro‐1‐sila‐3‐boranaphthalene species 7 are formed by the thermal elimination of MeOSiMe 3 from 1a/b or 1c or 1d , respectively. The boranes 3a, b undergo cyclodimerization at the B=C bond at 25 and 69°C, respectively, ...

Bei 25°C ist 2d lagerfähig, während sich 2c zu 5 cyclodimerisiert. In 2d , das bei 225 K kristallisiert, findet man bei 120 K ein lineares CBC‐Gerüst mit BC‐Bindungslängen von 154.7 und 136.1 pm.

This paper describes practical aspects of a novel approach to the sequential pattern mining named Context Based Sequential Pattern Mining (CBSPM). It introduces a novel ContextMapping algorithm used for the context pattern mining and an illustrative example showing some advantages of the proposed method. The approach presented here takes into consideration some shortcomings of the classic problem of the sequential pattern mining. The significant advantage of the classic sequential patterns mining ...

Sequential pattern mining is an important task for Web usage mining. In this paper we generalize it to the problem of mining context based patterns, where context attributes may be introduced both for describing the complete sequence (e.g. characterizing user profiles) and for each element inside this sequence (describing circumstances for succeeding transactions). Such patterns provide information about circumstances associated with the discovered patterns what is not present in the traditional patterns. ...

Sodium-glucose cotransporter 2 (SGLT2) inhibitors are a new class of antidiabetic drugs, acting by inhibiting the reabsorption of glucose in the kidneys. They turned out to improve cardiovascular and renal outcomes not only in patients with type 2 diabetes but also in nondiabetic patients. At present, they are more and more widely used in patients without diabetes. Since there were concerns that SGLT2 inhibitors may increase fracture risk in diabetes, the aim of the study was to examine the effect ...

Different signaling pathways have been studied in ankylosing spondylitis. New treatment options such as secukinumab could have an important role inhibiting the release of proinflammatory cytokine IL-17. The aim of this study was to compare the efficacy and safety of secukinumab in ankylosing spondylitis. A systematic review was conducted using MEDLINE and EMBASE databases to identify randomized clinical trials (RCTs) that assess the role of secukinumab in ankylosing spondylitis. The variables were ...

Abstract Polymers which contain inorganic elements are attracting considerable attention because they provide access to materials with interesting, unusual and potentially useful properties. In this paper we emphasize some of our recent work aimed at exploiting ring-opening polymerization as a route to new inorganic and organometallic polymers containing the main group element phosphorus. For example, attempts to prepare new polymers which also contain boron are reported. In addition, recent results ...

Abstract An important aspect of economic integration of the European Union is price convergence on digital single market. In this study, we propose a novel way to measure price dispersion in the e-commerce industry, using a custom made web-scraping tool. We target all the major price comparisons sites in the 26 EU member states, which enables us to collect price signals from thousands of retail shops operating on-line. We analyse pricing data of 182 branded products sold on-line across the EU, representing ...
