‐Triftosylhydrazone (DFHZ‐Tfs) as a Bench‐Stable Crystalline Diazo Surrogate for Diazoacetaldehyde and Difluorodiazoethane
study, we developed a bench-stable difluoroacetaldehyde N-triftosylhydrazone (DFHZ-Tfs) as an operationally safe diazo surrogate that can release in situ two low-molecular-weight diazoalkanes, diazoacetaldehyde (CHOCHN2 ) or difluorodiazoethane (CF2 HCHN2 ), in a controlled fashion under specific conditions. DFHZ-Tfs has been successfully employed in the Fe-catalyzed cyclopropanation and Doyle-Kirmse

)-H Bond via Tandem 1,5-HAT and Difunctionalization of Aryl Alkenes
A visible‐lightmediated γ‐hydroxyalkylation of ketones via C(sp3)‐H functionalization has been developed under redox neutral conditions. This protocol relies on the iminyl radical‐triggered 1,5‐HAT followed by oxyalkylation of alkenes, wherein C−C and C−O bonds were constructed in one step. This three‐component reaction features mild conditions, wide substrate scope and excellent functional group

The Brown hydroboration reaction, first reported in 1957, is the addition of B−H across an olefin in an anti‐Markovnikov fashion. Here, we solved a long‐standing problem on mild 1,3‐hydroborations of non‐activated cyclopropanes. A three‐component system including cyclopropanes, boron halides, and hydrosilanes has been developed for borylative ring‐opening of cyclopropanes following the anti‐Markovnikov
