Synthesis and reactions of poly(ethynyldialkylsilanes)

Synthesis and reactions of poly(ethynyldialkylsilanes)

A nucleophilic cleavage reaction of 2,2,5,5,8,8-hexamethyl-2,5,8-trisilanona-3,6-diyne, I, with several bases, occurs rapidly at room temperature in both polar and non-polar solvents. An attack occurs exclusively at the central silicon regardless of the steric requirements of the bases (alkyllithium...
