Dialkylamino Phosphorus Metal Carbonyls. 1. Mononuclear Derivatives from Reactions of Bis(diisopropylamino)phosphine with Metal Carbonyls

摘要

Bis(diisopropylamino)phosphine, (i-Pr2N)2PH, has recently become readily available through the LiAlH4 reduction of (i-Pr2N)2PCl. Metal carbonyl complexes of (i-Pr2N)2PN are of interest because they contain potentially reactive phosphorous-hydrogen and phosphorus nitrogen bonds. This paper describes a number of mononuclear (i-Pr2N)2ph metal carbonyl complexes as well as the cleavage of one or, in one case, both phosphorus-nitrogen bonds in such complexes with hydrogen halides to give the corresponding metal carbonyl complexes of the ligands i-Pr2NP(H)X(X = Cl, Br) and Br2PH.
