Herein, we report a protocol for visible-light-induced dearomative oxamination reactions of indole derivatives to afford functionalized spirocyclic products.

A new radical-mediated intramolecular arene C(sp2)–H amidation of 3-phenylpropanamides or [1,1′-biphenyl]-2-carboxamides was developed to prepare a series of 3,4-dihydro-2(1H)-quinolinone and phenanthridone derivatives in moderate to excellent yields (33–94%).

The first highly enantioselective conjugate addition of 2-acetyl azaarenes to α-substituted-β-nitroacrylates was successfully realized under mild conditions by a Ni(II)-bisoxazoline complex, providing the desired adducts bearing an all-carbon quaternary stereocenter in high yield with excellent enantioselectivity. The products obtained in this system could be readily converted into optically active β-amino esters, succinates, lactones, and lactams.

The photoelectric properties and catalytic activities of substituted triphenylphosphine and sulfur/selenium ligands supported aromatic triangular tri-palladium complexes 1-4, abbreviated as [Pd3]+, were investigated. The cyclic voltammogram of [Pd3]+ in CH3CN-nBu4NPF6...
