Lithio tert-butyl bis(trimethylsilyl)acetate, I, obtained by reaction of the corresponding ester, II, with lithium diisopropylamide (es l), reacts with aldehydes to give good yields of a-silylated vinyl esters (eq 2). As suggested previously for the mono-silyl analogue
nBuLi solution (5 mmol: in hexanej added. On warming to room temperature the original yellow solution changed color from green to reddish-brown. and gdS evolution was observed. After the mixture had been stirred at room temperature for 30 min the resulting clear yellow solution was refrigerated over
## Abstract Ethyl α‐hydroxymethylacrylate (EHMA) was synthesized from ethyl acrylate and paraformaldehyde, and converted to ethyl α‐chloromethylacrylate (ECMA) by reaction with thionyl chloride. ECMA was bulk polymerized at 65°C with α,α′‐azobis(isobutyronitrile) (AIBN) to give a homopolymer with a
