Abstract: A Brønsted base mediated stereoselective diphosphination of terminal alkynes with diphosphanes proceeds to deliver the corresponding (E)-1,2-diphosphinoethenes in good yields. The reaction of aromatic alkynes occurs efficiently in the presence of a catalytic amount of… read more here.

Abstract: Regioand stereoselective synthesis of N -substituted azole acrylonitriles has been achieved smoothly in N,N -dimethylformamide (DMF) in the presence of potassium carbonate (K2 CO3) as a base catalyst. N -Substituted azole acrylonitriles were obtained in… read more here.
