Abstract : Major achievements from this research project include the preparation and characterization of new types of dialkylaminophosphorus derivatives and their metal carbonyl complexes. Reductions with LiAlH4 of dialkylaminodichlorophosphines, R2NPCl2, having sufficiently large dialkylamino groups were found to lead to the corresponding dialkylaminophosphines, R2NPH2 (R2N = dicyclohexylamino and 2,2,6,6-tetramethylpiperidino) as very air-sensitive liquids. Dehalogenation of R2NPCl2 (R = isopropyl or cyclohexyl) with magnesium in tetrahydrofuran was found to give the corresponding cyclotetraphosphines (R2N)4P4; the corresponding biphosphines (iPr2N)2P2X2(X = Cl and Br) can be isolated from reactions of i(Pr2NPX2 with more limited quantities of magnesium. Keywords: Phosphorus, Silicon, Boron, Metal complexes, Dialkylamino, Cyclopolyphosphines, Metal carbonyls.
