2-(Tributylstannyl)-4,4-dimethyl-2-oxazoline (1) reacted with aroyl chloride smoothly without any palladium catalyst to give the unusual product, bis(N-aroyl-4,4-dimethyl-2-oxazolinylidene) in good yields. The reaction of 1 with other types of halide needed a palladium catalyst, and gave the corresponding 2-substituted-4,4-dimethyl-2-oxazoline in good yields.
2-(三丁基甲锡烷基)-4,4-二甲基-2-恶唑啉(1)在没有任何钯催化剂的情况下与芳酰氯顺利反应,得到不寻常的产物,双(N-芳酰基-4,4-二甲基-2-恶唑啉亚基)良好的收益。1与其他类型卤化物的反应需要钯催化剂,并以良好的收率得到相应的2-取代-4,4-二甲基-2-恶唑啉。
