Reactive E=C(p-p)π-Systems, XXVI. - Facile Synthesis of Phosphaalkenes of the Type HP=C(F)NR2 and the Phosphaalkyne P≡C-N(iPr)2The reaction of trifluoromethylphosphane CF3PH2 with secondary amines in a 1:3 molar ratio leads to the novel methylenephosphanes (phosphaalkenes) HP = C(F)NR2 [R = Me (1), Et (2), Pr (3), piperidine (4)] in yields between 40 and 60%. The analogous deuterium compound DP = C(F)NEt2 (5) is formed by the reaction of CF3PD2 with Et2ND. However, with di(isopropyl)amine the new phosphaalkyne P ≡ C—N(iPr)2 (6) is produced instead of the expected phosphaalkene.
