Acetonitrile → Chloro(2,6-di-tert-butyl-4-methylphenoxy)dimethylsilane

Participants

Reaction Steps

A mixture of 2,6-di-t-butyl-4-methylphenol (110 g, 0.5M), acetonitrile (500 ml), triethylamine (70 ml, 0.5M) and dichlorodimethylsilane (61 ml, 0.5M) was refluxed for 16 hours. The solvent was evaporated and the residue extracted with toluene (500 ml). The toluene extract was evaporated and the residue recrystallised from acetonitrile to give the title compound (90 g, 57%) m.p. 119°-121° (Found: C, 65 65; H, 9.4%. C17H29ClOSi requires C, 65.2; H, 9.3%).
