Abstract
Triethylvinyltin (I) reacted with diethyl malonate or ethyl acetoacetate in presence of DTBP to give only β-addition products : diethyl triethylstannylethylmalonate (IV) 37.6% or 3-ethoxycarbonyl-5-triethylstannyl-2-pentanone (V) 43.6%. Then several 5-triethylstannylethylpyrimidine derivatives (VIIIa, c, IXa, b, c) were synthesized from the reaction of IV or V with urea, thiourea and guanidine respectively except the case of IV with thiourea.
