Oxidative Homocoupling

Aerobic oxidative homocoupling of arylboronic acid under acidic aqueous conditions (pH 4.0) using bimetallic Au/Pd alloy nanoclusters stabilized by chitosan has been investigated. It was found that a Au0.81Pd0.19 catalyst (3.1 ± 0.8 nm) exhibited superior catalytic activities as compared to monometallic Au (2.3 ± 0.3 nm) and other series of bimetallic nanoclusters, giving the corresponding biaryls in nearly quantitative yield.

First Time

Two metal-free porphyrins H[Formula: see text]Pp (a, b) and four metalloporphyrins CuPp (a, b) and ZnPp (a, b) have been applied to lithium/thionyl chloride (Li/SOCl[Formula: see text] battery as the high efficient catalysts for the first time. Notably, the battery discharge time in blank is only 1080 s while that of Li/SOCl2 battery after adding porphyrin/metalloporphyrins is 1980 s for H[Formula: see text]Pp (a), 2160 s for H[Formula: see text]Pp (b), 1560 s for CuPp (a), 1320 s for CuPp (b), 1620 s for ZnPp (a), and 1680 s for ZnPp (b), respectively. Furthermore, the energy of the battery whose electrolyte contains the H[Formula: see text]Pp (a, b), CuPp (a, b) and ZnPp (a, b) increases by approximately 11.88–77.14% than that of the battery without them. And the metal-free porphyrins H[Formula: see text]Pp (a) or H[Formula: see text]Pp (b) exhibit higher catalytic activities than that of metalloporphyrins CuPp (a, b) and ZnPp (a, b). In addition, the possible reasons to explain the excellent results were also analyzed.
