The Group 14 (Si, Ge, and Sn), Group 15 (P, As, Sb, and Bi), and Group 16 (Se and Te) 2-trimethylsilyl-1-benzometalloles (7) were prepared by the reaction of the corresponding metal reagents with β,o-dilithio-β-trimethyl- silylstyrene intermediate (6), which was derived from phenylacetylene or o- bromoiodobenzene via three steps. The trimethylsilyl group in 7 could be readily removed by treatment with tetrabutylammonium fluoride to give the C- unsubstituted 1-benzometalloles (10).

The group 14 (Si, Ge, Sn), group 15 (P, As, Sb, Bi) and group 16 (S, Se, Te) (2-trimethylsilyl)-1-benzometalloles 5 have been prepared from phenylacetylene via three steps and converted into the corresponding C-unsubstituted benzometalloles 7 by detrimethylsilylation.
The preparation of (Z)-2-lithio-ortho-styryllithium via an ortho-directed lithiation
Ashe, Arthur J.,Savla, Paresh M.
, p. 1 - 4 (2007/10/02)
Lithiation of (Z)-2-lithiostyrene with t-butyllithium/TMEDA pentane led directly to (Z)-2-lithio-ortho-styryllithium. subsequent treatment of this dilithio compound with difunctional electrophiles allowed the preparation of a variety of benzoheteroles.

The title compound 5 can be easily synthesized by combination of two published procedures.It undergoes quantitative lithium cleavage of the exocyclic P-Ph bond, and phosphorus substituent exchange by reaction with t-butyllithium.The phosphindolyl anion di
