The phenylthio group as a new substituent on the 2-position of sterically protected 1-phosphaethenes

The phenylthio group was introduced to the sterically protected phosphaethene-system and 1-(phenylthio)-2-(2,4,6-trit-butylphenyl)-2-phosphaethenyllithium was generated. It has been shown that the lithium reagent behaves like a haloderivative, in terms of elimination, metalation, and coupling reaction, while the E/Z isomerization was observed for the phenylthio-derivative, and a 1,4-diphospha-1,3-butadiene as an oxidative coupling product was analyzed by X-ray.

A convenient synthesis of a sterically protected 1,4-diphosphabutatriene and its pentacarbonyltungsten complexes

1,4-Bis(2,4,6-tri-t-butylphenyl)-1,4-diphosphabutatriene was obtained by the copper-mediated coupling reaction of 1-halo-2-phosphaethenyllithiums. The 1,4-diphosphabutatriene formed mono- and bis-pentacarbonyltungsten complexes, and the X-ray analysis of

Formation of 6,8-di-tert-butyl-3,4-dihydro-4,4-dimethyl-1-phosphanaphthalene by the reaction of 2,2-dibromo-1-(2,4,6-tri-tert-butylphenyl)-1-phosphaethene with butyllithium

Sterically crowded 1-bromo-2-(2,4,6-tri-tert-butylphenyl)-2-phosphaethenyllithium gave 6,8-di-tert-butyl-3,4-dihydro-4,4-dimethyl-1-phosphanaphthalene by intramolecular insertion of an intermediary phosphinidene carbene species into one of the C-H bonds of the two o-tert-butyl groups.
