Syntheses and X-ray Structures of Novel Main Group Bis(dialkylamino)phosphinimides

Reactions of aminobis(dicyclohexylamino)phosphane with several aluminum trialkyls R 3 Al (R = Me, Et, t -Bu) yield the simple Lewis acid−base adducts (Cy 2 N) 2 P(H)N(H)AlR 3 (R = Me, 1; Et, 2; t -Bu, 3 ). Dimeric phosphiniminoalanes [(Cy 2 N) 2 P(H)NAlR 2 ] 2 (R = Me, 4; Et, 5 ) were obtained by reactions of aminobis(dicyclohexylamino)phosphane with the corresponding dialkyl aluminum hydride R 2 AlH. X-ray structure analyses were obtained from 1, 3, 4, and 5 .
