✦ Synopsis

Tetranethoxyethylene (TIIE) is a highly nucleophilic alkene that reacts with methanol, malononitrile or benmic acid to give the addition products, pentaoethoxyethane, 1,2,2~trimethoxyethyltdenemalononitrile and 1,1,2,2-tetramethoxyethyl benxoate respectively'. Roreover, the last product decomposes thermally to give methyl benzoate and methyl dimethoxyacetate'. According with these facts, the reaction of THE with bdicarbonyl compounds can give the reaction products indicated in Scheme 1 HE0 OHe 'C-C' + ReO'
