Abstract

Abstract Halosilylenoids, stable at room temperature (Tsi) X 2 SiLi (Tsi= C (SiMe 3) 3, X= Br, Cl), were synthesized from the reaction of TsiSiX 3 with lithium naphthalenide. Bromosilylenoid reacted with tBuOH and MeI both at− 78 C and at room temperature to give (Tsi) HSiBr 2 and (Tsi) MeSiBr 2, respectively, in high yields; this clearly shows its nucleophilicity. In the reaction of bromosilylenoid with methanol, 2-propanol, and 2, 3- ...
