2,2-Dimethylpropylidinphosphan, eine stabile Verbindung mit einem Phosphoratom der Koordinationszahl 1 (Acyl- und Alkylidenphosphane ; 15)

Abstract

In the presence of small amounts of solid sodium hydroxide, (2,2-dimethyl-1-(trimethyl-siloxy)propylidene]-trimethylsilylphosphine reacts at + 20° C to give hexamethydisiloxane and 2,2-dimethylpropylidynephosphine (2). In contrast to similar alkylidynephosphines this compound is stabIe at room temperature. The IR and mass spectrum are discussed, and 1 H, 13 C and 31 PNMR spectral data are given.
