C(sp3)-H bonds and chloroformates has been accomplished via nickel and photoredox catalysis. A diverse range of feedstock chemicals, such as (a)cyclic alkanes and toluenes, along with late-stage intermediates, undergo intermolecular C-C bond formation to afford esters under mild conditions using only 3 equiv of the C-H partner. Site selectivity is predictable according to bond strength and polarity

Migration of a trimethylsilyl group from oxygen to the α-carbon (retro- [1,3]-Brookrearrangement) in silyl ketene acetals is catalyzed by LPDE/methyl triflate under mild conditions.
