193 + 222 nm enhanced photolysis of selectively deuterated 2-chloropropane. A direct investigation of site-specific bond cleavage in the intermediate photofragment (s)

Selectively deuterated 2-chloropropane (CD 3CHClCD 3) is used to investigate photoinduced, site-specific CH (or CD) bond cleavage. In this study, a two-color photolysis approach is employed to create an intermediate photofragment(s) and then produce a neutral H or D atom from that photofragment(s)...

Description
Summary:Selectively deuterated 2-chloropropane (CD 3CHClCD 3) is used to investigate photoinduced, site-specific CH (or CD) bond cleavage. In this study, a two-color photolysis approach is employed to create an intermediate photofragment(s) and then produce a neutral H or D atom from that photofragment(s). On a per site basis, the experimental results suggest that 222 nm photolysis of an intermediate, most likely the isopropyl radical, will preferentially induce carbon-hydrogen bond cleavage at the 2-position — not the lowest energy pathway.
