A stable, multifunctional (diboronmethyl)iodide reagent (CH(Bpin)2I) was synthesized for the photoinduced cyclopropanation of alkenes, providing an array of 1,2-substituted cyclopropylboronates. The transformation exhibits operational simplicity, broad substrate scope, excellent functional-group compatibility, high chemo- and diastereoselectivity, and practicality for the late-stage modification of

The development of effective strategies to forge C–O and C–S bonds in diverse chemical spaces is of considerable interest in synthetic organic chemistry. Herein we report a versatile approach for the modularsynthesis of structurally diverse (thio)ethers and (thio)esters via homologative coupling of α-halodiborylmethane followed by transformation of the introduced diborylmethyl group. This method accommodates
