Methoxy isothiocyanate has been identified as a product of pyrolysis of the silver salt of N-methoxydithiocarbamic acid. It is also formed on FVT of 1-(N-methoxythiocarbamoyl)imidazole and 1-(N-methoxythiocarbamoyl)-1,2,4-triazole. Methoxy isothiocyanate was identified by IR spectroscopy in argon matrices at 10 K supported by good agreement with the ab initio and DFT calculated spectrum. Isopropoxy isothiocyanate was generated from the corresponding silver salt in a similar manner. The oligomerization of MeONCS to trithiolanes and tetrathianes is also described.
甲氧基异硫氰酸酯已被确认为N-甲氧基二硫代氨基甲酸银盐的热解产物。在1-(N-甲氧基硫代氨基甲酰)咪唑和1-(N-甲氧基硫代氨基甲酰)-1,2,4-三唑的FVT过程中也会形成甲氧基异硫氰酸酯。通过红外光谱在10K的氩矩阵中对其进行鉴定,与从头计算和DFT计算的光谱高度一致。异丙氧基异硫氰酸酯以类似方式从相应的银盐生成。还描述了甲氧基异硫氰酸酯的寡聚化,生成三硫代环戊烷和四硫代环己烷。
