A radical [1,4]-oxygen-atom transfer has been realized by the reaction of linear alkyne-tethered ketoximes and ethynylbenziodoxolones (EBX) under sequential catalytic conditions. Mechanism studies indicate that the O atom transfer experiences a cascade O atom radical cyclization/alkynylation/N–O bond photocleavage and subsequent N,O-diradical rearrangement. By the diversification of catalytic sequences, a series of structurally important 3H-pyrrol-3-ones and chlorinated furo[3,2-b]pyrroles are divergently synthesized along with an O atom shift under the catalysis of Cu/Ir photosensitization and Cu/Ir photosensitization/AlCl3, respectively.

Electrochemical propargylation of aldehydes and ketones with unsubstituted or α-substituted propargylic bromides using platinum cathode and zinc anode proceeded efficiently under mild conditions to give the corresponding homopropargyl alcohols exclusively

A monodentate phosphine, 8-diphenylphosphino-8'-methoxy-1,1'-binaphthyl, was shown to be active as a ligand in palladium-catalyzed reactions, including the reduction of allylic carbonates with formic acid, hydrosilylation of a terminal olefin, and hydroboration of but-1-en-3-yne, even though it has a highly hindered lone pair.
NEW CONVENIENT APPROACH TO THE PREPARATION OF (Z)-ALLYLIC BORONATES VIA CATALYTIC 1,4-HYDROBORATION OF 1,3-DIENES WITH CATECHOLBORANE

Hydroboration of 1,3-butadiene, isoprene, myrcene, 2,3-dimethyl-1,3-butadiene, and 1,3-cyclohexadiene with catecholborane(1,3,2-benzodioxaborole) in the presence of Pd(PPh3)4 or Rh4(CO)12 catalysts proceeds smoothly to provide 2--1,3,2-benzodioxaboroles in very high regio- and stereoselectivity.
