Catalylic diastereo- and enantioselective hydroalkylation of 3,3-disubstituted cyclopropenes with Co-homoenolate generated in situ from ring-opening of easily accessible cyclopropanols promoted by a chiral phosphine–cobalt complex is presented. Such a process represents the unprecedented and direct introduction of a wide range of functionalized alkyl groups without the need of pre-formation of stoichiometric amounts of organometallic reagents onto the cyclopropane motif, affording multi-substituted cyclopropanes in up to 99 % yield with >95:5 dr and 98:2 er. Functionalization of the products delivered enantioenriched cyclopropanes that are otherwise difficult to access.
Visible-light-driven selective alkenyl C-P bond cleavage of allenylphosphine oxides

An efficient method for highly selective alkenyl C-P bond cleavage, enabled by organic dyes and visible-light irradiation, was developed. This novel protocol involves a highly regioselective radical pathway initiated by singlet oxygen, affording diverse a
Rhodium(III)-Catalyzed Controllable C?H Bond Functionalization of Benzamides and Vinylidenecyclopropanes: A Directing Group Determined Reaction Pathway

A controllable rhodium(III)-catalyzed C?H bond activation of benzamides and vinylidenecyclopropanes (VDCPs) by changing the directing group from C(O)NH–OPiv to C(O)NH–OBoc has been disclosed, affording two different major products in good yields under mild condition, respectively. The substrate scope has been investigated and a plausible reaction mechanism has been also proposed on the basis of previous literature. (Figure presented.).
