The reaction chemistry between 1,4-dilithio-1,3-butadienes (dilithio reagents for short) and PhSiH3 has been investigated. Direct substitution of two hydride ions from PhSiH3 with the dilithio reagents led to multisubstituted siloles (silacyclopentadienes) in diethyl ether solution, with the concomitant generation of LiH. When THF was used as the solvent, the reaction between PhSiH3 and 1,4-bis(silyl)
