The chemistry of phosphorus compounds containing Si-N-P andor Si-C-P linkages is usually quite different from that of the nonsilylated analogues. On the one hand, the steric bulk and Pi acceptor properties of silyl groups can be used to kinetically stabilize a variety of low-coordinate phosphorus systems. Alternatively, the Si-N or Si-C bonds may serve as reactive sites so that processes such as intramolecular silyl group rearrangements and condensation reactions due to silane elimination are commonly found. These points are particularly well illustrated by the synthesis and reactivity of silylated ami no methylene phosphines. As a continuation of these studies, we report here several reactions which include some novel additions to the P-C double bond, metal complexation, and oxidative bromination. We were primarily interested in assessing the potential of compounds such as 1 as synthetic reagents in organonphosphorus and organometallic chemistry. A secondary objective of this study was to more closely compare the reactivity of 1 with its isoelectronic i mi nophosphine analogue, Me3Si2NPNSIMe3.8.
