✦ Synopsis
Allylic phosphine systems were studied as phosphorus-carbon double bond precursors. I -Phenyl and Ibutyl-1 -phospha-l,3-dienes were generated by pyrolysis at 350-460°C of the corresponding diallyl phosphines in a stirred-flow reactor. The unsubstituted phosphadienes generated in this manner
dimerized; the formation o f [ 4 + 21 cycloaddition products was confirmed by N M R and mass spectroscopic analysis. 31P N M R data of the I-phospha-I,3-dienes were obtained.
