Phosphasilene synthesis and reactivity: an improved route to 1-(2,4,6-tri-tert-butylphenyl)-2-tert-butyl-2-(2,4,6-tri-isopropylphenyl)phosphasilene

A new route was developed for the synthesis of a specific phosphasilene, 1-(2,4,6-tri-tert-butylphenyl)-2-tert-butyl-2-(2,4,6-tri-isopropylphenyl)phosphasilene (1e).Several novel phosphasilenes (1) with various substituents on phosphorus have been synthesized.The influence of the substituents on the phosphorus and silicon chemical shifts and the stability of the phosphasilenes is analyzed.The chemical reactivity of 1e has been investigated.

RECENT DEVELOPMENTS IN PHOSPHASILENE CHEMISTRY

An alternative route to phosphasilenes is discussed and several new phosphasilenes, with variation of the substituents on phosphorus, have been synthesized.The influence of the substituents on the phosphorous and silicon chemical shifts, as well as on the stability of the phosphasilenes is analyzed.The chemical reactivity of one of the phosphasilenes was explored.

PHOSPHASILAETHENES

The synthesis, stability, and spectroscopic properties of several phosphasilaethenes ArP=SiR'R'' are described.It is concluded that the P=Si bond is a typical p(?)-p(?) bond which is highly polarized (Pδ-, Siδ+).
