Synthesis of (1,3-Disilylpropenyl)Phosphines
Abstract
Recently, there has been considerable interest in the preparative, structural, and coordination chemistry of phosphadienes, the acyclic, conjugated butadiene analogues in which one or more of the carbon atoms are replaced by 2- coordinate phosphorus centers. We have reported, for example, the synthesis and some novel oxidation/cyclization reactions of the 1-phosphadiene 2 which is kinetically stabilized by the steric bulk and pi-acceptor properties of the Me3Si groups along the P =C-C=C backbone. Because of their potential as precursors to phosphadienes and novel phosphorus heterocycles and as new, multidentate ligands in organometallic systems, we have conducted a more detailed investigation of the chemistry and related 1,3- disiylypropenylphosphines. Accordingly, we report here the synthesis and NMR structural characterization of a series of new phosphines which contain the 1,3- bis(trimethylsily)propenyl substituent. Phosphines.
