s. The silicon-chlorine bond of 1-alkyl-3-chlorotetramethyldisiloxanes reacts with alkyllithiumreagents at higher temperatures (0°C). Both the silicon-chlorine bonds of 1,5-dichlorohexamethyltrisiloxane react competitively with alkyllithiumreagents at − 78°C. No cleavage of siloxane bonds by alkyllithiumreagents is observed under these conditions. Spectral properties of a number of 1-alkyl-3-hy
