An efficient and highly selective Ir-catalyzed cage boron alkenylation of o-carboranes with diarylacetylenes coupled with 1,2-aryl migration has been developed, leading to B–H geminal addition products via vinylidene rearrangement.
An unprecedented Ir(III)-catalyzed C–H activation/amination/annulation of 2-phenyloxazoles with anthranils for the highly selective preparation of acridone derivatives in one-pot under controlled conditions is reported.
The rhodium(III)-catalysed ortho-C–H alkenylation of NH-sulfoximine using readily available vinylsilanes has been achieved. The vinylsilane groups can bes electively changed into a variety of substituents.
An efficient Ir(III)-catalyzed decarbonylative annulation of salicylaldehydes with cyclohexane-1,3-diones has been achieved via the in situ generated iodonium ylides.
A redox-neutral access to spirooxazine-pyrans has been realized via Rh(III)-catalysed [3+3] cascade spirocyclization of benzo[b][1,4]oxazines and 1-diazonaphthalen-2(1H)-ones under extremely mild reaction conditions.
