Rh(III)-Catalyzed C-H Amidation of Indoles with Isocyanates.
The rhodium(III)-catalyzed direct amidation of indoles and pyrroles with aryl and alkyl isocyanates is described. These transformations provide a facile and efficient construction of C2-amidated N-heterocyclic scaffolds.

متن کاملRhodium-catalysed addition reaction of aryl- and alkenylboronic acids to isocyanates.
The addition reaction of aryl- and alkenylboronic acids to isocyanates is catalysed by a rhodium(I) complex, affording secondary amides under mild conditions.
متن کاملThe role of isocyanates in fire toxicity
Isocyanates are a group of low molecular weight, highly reactive compounds with a functional isocyanate group. The main human exposure route is via inhalation of airborne isocyanates, although dermal exposure has also been reported. The inhalation of isocyanates is associated with severely adverse health effects such as asthma, inflammation in the respiratory tract and cancer. During thermal de...
متن کاملOccupational asthma due to isocyanates.
162 subjects who had been exposed to isocyanates, who had developed symptoms during the exposure period, or in the evening or night and, therefore, had a history compatible with isocyanate-induced asthma, were studied with inhalation challenge testing to isocyanates (toluene diisocyanate and methylene diphenyl diisocyanate) and methacholine, because they were suspected of having occupational as...
