Cobalt-catalyzed intramolecular C-N and C-O cross-coupling reactions: synthesis of benzimidazoles and benzoxazoles.

Cobalt(ii)-complex catalyzes efficiently the intramolecular C-N and C-O cross-couplings of Z-N'-(2-halophenyl)-N-phenylamidines and N-(2-bromophenyl)benzamides to afford the corresponding substituted benzimidazoles and benzoxazoles in the presence of K(2)CO(3) at moderate temperature. The protocol is general, air stable and affords the products selectively in moderate to high yield.

This paper examines steady states of an overlapping generations economy with a given distribution of household locations over a one-dimensional interval. Parents decide whether or not to educate their children. Such decisions are affected by location: parental aspirations depend on the earnings of their neighbors. At the same time, economy-wide wages endogenously adjust to bring factor supplies...

Copper-free Sandmeyer cyanation of arenediazonium o-benzenedisulfonimides.

Arene and heteroarenediazonium o-benzenedisulfonimides can be used as efficient reagents in Sandmeyer cyanation. This work reports such reactions carried out by us under very mild conditions using tetrabutyl ammonium cyanide as a safe cyanide source and, interestingly, without the need for a Cu catalyst. The reactions have given rise to aryl nitriles in good yields (25 examples, average yield 7...
