together with two kinds of byproducts, 3-(N-methylthiocar-bamoyl)-2-methyliminothiazolidine 4 and N,N′-dimethyl-N-(2-thiazolin-2-yl)thiourea 5. Thermal isomer-ization of 5 to 4 was observed. The structures of the byproducts were confirmed by X-ray crystallography.
2-溴乙胺1与甲基异硫氰酸酯2在温和的条件下反应,以2-甲基-氨基-2-噻唑啉3为主要产物,并与两种副产物3-(N-甲基硫代氨基苯甲酰基)-2-甲基亚氨基噻唑烷4和N,N′-二甲基-N-(2-噻唑啉-2-基)硫脲5。观察到5至4的热异构化。通过X射线晶体学证实了副产物的结构。
