ABSTRACT Secondary phosphine chalcogenides, R2PX (R═(CH2)2Ph, Ph; X = S, Se), react with divinyl chalcogenides, (CH2═CH)2Y (Y = S, Se, Te), at the 2:1 molar ratio (80–82°C, 56–80 h) in the absence of both catalysts (initiators) and solvents to quantitatively afford the corresponding anti-Markovnikov diadducts. Even at the equimolar reactant ratio, the diadducts are the major products, though monoadducts
摘要 二级膦硫属化物 R2PX (R=(CH2)2Ph, Ph; X = S, Se) 与二乙烯基硫属化物 (CH2=CH)2Y (Y = S, Se, Te) 以 2:1 的摩尔比反应在不存在催化剂(引发剂)和溶剂的情况下,比例(80-82°C,56-80 小时)以定量提供相应的反马尔可夫尼科夫二加合物。即使在等摩尔反应物比率下,二加合物也是主要产物,但也会形成单加合物。当Y=Te时,得到乙烯基膦硫属化物和金属Te,表明二乙烯基碲化物作为乙烯基化剂。图形概要
