A new route to silyl-substituted cyclobutenones and silylketenes

Benda, Konstantin,Knoth, Tanja,Danheiser, Rick L.,Schaumann, Ernst

scheme or table, p. 46 - 48 (2011/02/25)

2-Silyl-cyclobutene(di)ones are obtained by an addition/substitution approach on dimethyl squarate using silyl anions. The acetal and in particular the thioacetal derivatives readily undergo electrocyclic ring opening to reactive silyl(vinyl)ketenes.
