In this paper we describe the first examples of carbene transfer with donor-acceptor diazoacetates and the silver tris(pyrazolyl) borate complex {HB[3,5-(CF3)2Pz]3}Ag(THF). These reactions generally proceed in good yields

(Figure Presented) Primary C-H bond activation! A Rh complex of bis-pocket porphyrin I catalyzes carbenoid insertion into the C-H bonds of n-alkanes with a primary/secondary selectivity (per C-H bond) of up to 11.4:1 (see picture). Enantioselective secondary C-H bond functionalization catalyzed by a Rh complex of Halterman's chiral porphyrin features up to 93% ee. These reactions exhibit up to 6477 turnovers after the catalyst was recycled five times.
The thionophosphate-thiolophosphate photoisomerization proceeds predominantly through a non-chain radical pathway. Synthetically viable benzylation of tetrahydrofuran, propan-2-ol and olefins

The photoirradiation of thionophosphates, ROP(S)(OEt)2, derived from benzyl and vinylogously benzyl alcohols in CH3CN, with a Hanovia medium-pressure mercury lamp in a quartz vessel leads to the formation of the corresponding thiolophosphates, RSP(O)(OEt)2, through a non-chain radical pathway. This behavior of thionophosphates is unlike that of the related phosphates, which react through ionic dissociation-recombination processes. When the irradiation is conducted in solvents such as PriOH, THF and toluene, benzylation of these solvents takes place in synthetically respectable yields. Irradiation of thionophosphates in CH3CN leads to a convenient allylic benzylation of olefins.
