A new procedure for a direct conversion of 1,3-dienes into N,N-dimethyl insaturated tertiary amides is reported. η3-Allyltitanium(III) complexes generated in situ from various dienes reacted regiospecifically with dimethylcarbamoyl chloride to afford products in good to moderate yields. Acyclic, cyclic, incorporated into the polyene systems, and even sterically demanding dienes can be employed.
报道了一种新的将1,3-二烯直接转化为N,N-二甲基不饱和叔酰胺的方法。η 3产生-Allyltitanium(III)配合物在原位从各种二烯与甲基氨基甲酰氯区域专一性反应,得到的产品以优良至适中的产率。可以使用非环状的,环状的,并入多烯体系中的,甚至在空间上苛刻的二烯。
