Reactions of aminobis(dicyclohexylamino)phosphane with several aluminum tri
alkyls R3Al (R = Me, Et, t-Bu) yield the simple Lewis acid-base adducts (Cy
2N)(2)P(H)N(H)AIR(3) (R = Me, 1; Et, 2; t-Bu, 3). Dimeric phosphiniminoalan
es [(Cy2N)(2)P(H)NAIR(2)](2) (R = Me, 4; Et, 5) were obtained by reactions
of aminobis(dicyclohexylamino)phosphane with the corresponding dialkyl alum
inum hydride R2AlH. X-ray structure analyses were obtained from 1, 3, 4, an
d 5.
