Resumo

The Grignard-addition of phenylethynylmagnesium bromide to 1,2,4,5-tetraformylbenzene (1) and the subsequent oxidation of the primary formed alcohol (2) afford the l,2,4,5-tetra(phenylpropynoyl)benzene (8). The reaction of 8 with tris(triphenylphosphin)-rhodium-(I)chloride leads to the Rh-complex (4), which further reacts with acetylenederivates and chalcogens to form the quinoid compounds 5a-c and 6, 7.
