Rhodium-catalyzed intramolecular C-H silylation by silacyclobutanes

Silacyclobutane was discovered to be an efficient C-H bond silylation reagent. Under the catalysis of RhI/TMS-segphos, silacyclobutane undergoes sequential C-Si/C-H bond activations, affording a series of π-conjugated siloles in high yields and regioselectivities. The catalytic cycle was proposed to involve a rarely documented endocyclic β-hydride elimination of five-membered metallacycles, which after reductive elimination gave rise to a Si-RhI species that is capable of C-H activation. Old reagent, new reactivity: Silacyclobutane was discovered to be an efficient C-H bond silylation reagent under the catalysis of Rh/TMS-segophos. This new reactivity was attributed to a key Si-RhI intermediate formed through a Si-C activation, endocyclic β-H elimination and reductive elimination cascade. A wide array of siloles was obtained in high yields and excellent regioselectivities.
