Photolysis of Solutions of 3-tert-Butylperoxy-3-methyl-1-butyne

摘要

Photolysis of solutions of 3-tert-butyl-3-methyl-1-butyne in CD_3OD and C_6D_(12) was studied by means of ~1H NMR spectroscopy, chemical nuclear polarization of the reaction products in the range 213-333 K, and kinetic measurements. It is shown that 3-tert-butyl-3-methyl-1-butyne decomposes primarily from a singlet electronic state. A scheme is proposed of the most probable reactions involving the radicals formed and solvent molecules. It is found that secondary processes play an important role in the initiation of the chemical nuclear polarization and the photolysis mechanism.
