Dual Catalysis

AbstractThe combination of transition-metal catalysis and visible-light photocatalysis offers opportunities for the development of unique new forms of reactivity. Presented in this chapter is an overview of the various strategies that can be used to design these dual catalytic transformations. Emphasis is placed on understanding the specific role that a photocatalyst can play in augmenting the reactivity of a substrate or cocatalyst to achieve otherwise challenging transformations.

Benzothiazole Derivatives

AbstractA synthesis of benzothiazole derivatives through the reaction of 2-halo-N-allylanilines with K2S in DMF is developed. The trisulfur radical anion S3·–, which is generated in situ from K2S in DMF, initiates the reaction without transition-metal catalysis or other additives. In addition, two C–S bonds are formed and heteroaromatization of benzothiazole is triggered by radical cyclization and H-shift.
