Site-selectivity in C(sp3)–H functionalization of aliphatic alcohols and alkanes was studied using the decatungstate anion as a photocatalyst. In the case of aliphatic alcohols, C–H bond α to the hydroxy group was preferentially functionalized. The α-site-selectivity is rationalized by polar effects imparted by the hydroxy group in the SH2 transition states. In contrast, C–H functionalization of alkanes was largely affected by steric effects.

The reaction of various types of organic halides with electron deficient olefins under the influence of NiCl2 × 6 H2O in the presence of zinc and pyridine leads to formal addition products of hydrocarbons to CC-double bonds in good yield.
