Simple Preparation of Aryl Telluroesters and (2Z)-β-(Aryltelluro) cinnamic Esters
摘要:
Simple preparation of aryl telluroesters from reaction of tellurium powder and aryl Grignard reagents then acylation with acyl chlorides. Addition of telluroesters to arylpropiolates gave (2Z)-beta-aryltelluro-alpha, beta-unsaturated esters with high stereoselectivity.
