Laser-jet photolysis of 1,8-bis(substituted-methyl)naphthalenes; the effect of heteroatom leaving groups on the two-photon C–C bond formation
Abstract
The formation of acenaphthene 4 by laser-jet photolysis of 1,8-bis(phenoxyrmethyl)-(1a), 1,8-bis(phenylthiomethyl)-(1b) and 1,8-bis(phenylselenomethyl)-naphthalene (1c) strongly depends on the hetroatom of the leaving group; the increasing order of naphthalene consumption was 1c≈1b > 1a, whereas that for the formation of 4 was 1c > 1a > 1b.
