| Abstract: | Photochemistry, synthesis, nucleophilic addition photoreaction, low temperature photolysis, and quantum yield calculations of representative members have been studied in understanding the mechanism of the photofragmentation of mesoionic 1,3,4-thiadiazoles. Quantum yield calculations suggest self quenching and unimolecularity in the ring opening reaction while timed interval IR recording shows the formation of heterocumulenes during photolysis. |
