The known methylenephosphanes 1a-e react with lithio-α-chloroorganyls 2a,b to give the bismethylenephosphoranes 3a-f in high yields.The compounds 3c-f represent the first mixed substituted λ5?3-bismethylenephosphoranes, that except 3e,f could be isolated.Products 3e,f rearrange to the new phosphiranes 6a,b.The reaction of the methylenephosphane 1b with diphenyldiazomethane (4) leads via spectroscopic conceivable dihydrodiazaphosphole 5 to compound 3e.The course of the reactions, the spectroscopic data as well as the X-ray structure analyses of 3d and 6a are discussed.
