Bis(trimethylsilyl)acetylene

CAS: 14630-40-1

Bis(trimethylsilyl)acetylene (bis-TMS) is a reactive ancillary that can be used in polymerization reactions as an initiator. The bis-TMS is prepared by reaction of trimethylsilyl chloride with acetylene to form the trimethylsilyl acetylene, which is then reacted with copper to generate the bis-TMS. Bis-TMS reacts with nucleophiles such as alcohols and amines to produce polymers through a nucleophilic attack. It also has been used for sample preparation for NMR spectra. Bis-TMS is a synthetic compound that has been characterized using nmr spectroscopy and analytical methods. The molecular formula of bis-TMS is C8H16Si2 and its molecular weight is 196.13 g/mol. The chemical structure of bis-TMS consists of two benzyl groups connected by a single carbon bond at the 3 o'clock position on the central
