Efficient Approach

An efficient approach has been developed for the construction of quinazolin-4(3H)-ones by the selective anodic dehydrogenative oxidation/cyclization of benzylic chlorides and 2-aminobenzamides. The method features acceptor-free and metal-free dehydrogenation of amines to imines; a subsequent intermolecular addition provides the products in moderate to good yields.

Electrochemical Synthesis Of Ammonia

3D-graphene provide abundant space for N2, and the carbon–sulfur bonds provides a continuous supply of electrons for N2 reduction. A remarkably large NH3 yield of 38.81 μgNH3 mgcat−1 h−1 and FE of 7.72% for N2 reduction was obtained.
