UEBER EINIGE REAKTIONEN DER DIALKYLBENZYLPHOSPHINIMIDE

Wannagat, Ulrich,Muenstedt, Rainer

, p. 233 - 238 (2007/10/02)

Dialkylbenzylphosphine imides C6H5CH2-PRR'=NR'' (R,R'=CH3, C2H5; R''=H, CH3, Si(CH3)3) react with aliphatic and aromatic aldehydes in benzene solution on heating to 80 deg C directly and in high yields according to a Horner-Wittig-reaction with formation of an olefine whereas ketones like benzophenone and acetophenone only perform an O/NR'' exchange (R''=H).
