摘要：

Laser UV irradiation at 300 nm of 1,3,4,6-tetrathiapentalene-2,5-dione 1 isolated in argon matrix at 1 OK yields CO, CS2 and SCO by two competitive pathways. The reaction was monitored by FTIR spectroscopy. The reaction products were assigned by comparison of their infrared spectrum with those obtained from literature data and the ab initio RHF/DZP calculated spectrum for 1 was perform. The kinetic data shows similar rate constant for the two processes (about 5 10(-2) min(-1)). Irradiation of carbonyl sulfide at 260 nm yields carbon monoxide and S atoms which react with carbon atoms trapped in the same matrix cage to yield CS2.
