Abstract

Triphosgene was decomposed quantitatively to phosgene by chloride ion. The reaction course was monitored by IR spectroscopy (React-IR), showing that diphosgene was an intermediate. The methanolysis of triphosgene in deuterated chloroform, monitored by proton NMR spectroscopy, gave methyl chloroformate and methyl 1, 1, 1-trichloromethyl carbonate in about a 1: 1 ratio, as primary products. The reaction carried out in the ...
