Organic transformations mediated by photoredox catalysis have been at the forefront of reaction discovery. Recently, it has been demonstrated that binuclear Au(I) bisphosphine complexes, such as [Au2(μ-dppm)2]X2, are capable of mediating electron transfer to nonactivated bromoalkanes for the generation of a variety of alkyl radicals. The transfer reactions of bromine, derived from nonactivated bromoalkanes, are largely unknown. Therefore, we propose that unique metal-based mechanistic pathways are at play, as this binuclear gold catalyst has been known to produce Au(III) Lewis acid intermediates. The scope and proposed mechanistic overview for the formal bromine atom transfer reaction of nonactivated bromoalkanes mediated by photoredox Au(I) catalysis is presented. The methodol. presented afforded good yields and a broad scope which include examples using bromoalkanes and iodoarenes. In the experiment, the researchers used (Bromomethyl)cyclopropane(cas: 7051-34-5SDS of cas: 7051-34-5)
(Bromomethyl)cyclopropane(cas: 7051-34-5) is used as a synthetic building block for the introduction of the cyclopropylmethyl group. It was also used in the synthesis of 1,4-dienes via iron-catalyzed cross-coupling with alkenyl Grignard reagents.SDS of cas: 7051-34-5
