Low temperature photochemical studies
ABSTRACT Low temperature (8–77 K) photochemical studies directed toward elucidation of mechanism by identification of primary products and the synthesis of highly reactive molecules are described. A brief summary of the experimental approach is presented. An example of the direction low temperature experiments can provide for the synthesis of structurally complex molecules at room temperature is given. The synthesis and photochemical interconversion of various molecules on the C3H4 and C4H4 energy surfaces, benzyne, and α-lactones are described.
