Abstract

Thermal reactions of 1,2,3-triazines were investigated using neat thermolysis and flash vacuum thermolysis (FVT). Neat thermolysis afforded the products which were derived from intermolecular reaction, whereas unimolecular degradation occurred by FVT to give alkyne, nitrile and nitrogen. The selectivity of the reaction was considered using molecular orbital calculations.
