Conclusions 1. The 1,4-diphosphabuta-1,3-dienes S-trans-4,4′-didehydrobis-(5-methyl-2-phenyl-1,2,3-diazaphosphole (and diazaarsole), and S-trans-4,4′-didehydrobis-(2,5-diphenyl-1,2,3-diazaarsole) have been obtained. The structures of the first two compounds have been established by x-ray diffraction analysis. 2. 4,4′-Didehydrobis-(5-methyl-2-phenyl-1,2,3-diazaphosphole) has been obtained by UV irradiation of 5-methyl-2-phenyl-1,2,3-diazaphosphole. 4,4′-Didehydrobis-(2-phenyl-5-R-1,2,3-diazaarsoles) (R=Ph, Me) are not formed under similar conditions, but have been obtained by reacting the 2-phenyl-5-R-1,2,3-diazaarsoles with methylphenyldiazomethane and cyclohexanone.
