Bräunling, and K. Schneider, Chem. Ber. 101, 879 (1968). 3 For ease of discussion of their 1H-NMR spectra the C atoms of the phenanthrene portions of (2) and (4) are numbered as is usual in phenanthrenes. 4 Correct elemental analyses and molecular weights were obtained for these compounds; the spectroscopic data accord with the structures assumed. 5 F. Bohlmann and R. Miethe, Chem. Ber. 100, 3861 (1967). 6 We thank Dr. W. Brügel, BASF Ludwigshafen, for recording this spectrum. 7 In this comparison it must, nevertheless, be remembered that in (4), 12-H, 21-H and, to a smaller extent, also 4-H, 5-H are under the deshielding influence of the anisotropy of the diacetylene group, although this shifts these signals by no more than 0.5 ppm to lower field strength, as shown by the comparison with the spectrum of (3).
