1,1-Dialkyl(1,1-diaryl)-4-R-1-silacyclohexadienyl anions ( 1 ) are available by ether cleavage of the corresponding, 1,1-dialkyl(1,1-diaryl)-4-methoxy-4-R-1-silacyclohexa-2,5-dienes ( 4 ), or by deprotonation of the 1,1-dialkyl(1,1-diaryl)-4-R-1-silacyclohexa-2,4-dienes ( 3 ) - which are available from4 - with n-BuLi or LDA resp.

Review

Reproducible Reaction

Summary:

Synthesis of various silacycles has been reported. 

The Reaction of Interest:

Synthesis of t-BuSiHCl2 (18.5%, 50 mmol) via reaction of HSiCl3 (2 equiv) with t-BuLi.

Practical Observations:

  •  The reaction is reproducible, however 2 equiv of HSiCl3 is not...
