Thirty semicarbazone and thiosemicarbazone derivatives (2a–w and 4a–g) from chalcones containing furan and thiophene ring were designed and synthesized. They were characterized by IR, 1H NMR, 13C NMR and HRMS. The crystal structure o
Transition metal-free domino aryl-aryl coupling/phospha-Michael addition of diarylphosphinite to α,β-unsaturated ketones triggered by alkaline hydrolysis of (4-(2-alkenoyl)phenyl)triarylphosphonium salts

Alkaline hydrolysis of a variety of (4-(2-alkenoyl)phenyl)triarylphosphonium bromides is reported. This hydrolysis triggers coupling of 4-(2-alkenoyl)phenyl with one aryl via phosphorus(V). Both diarylphosphinite and an α,β-unsaturated ketone are in situ generated and then undergo phospha-Michael addition to provide β-diarylphosphoryl ketones bearing a biaryl moiety in 27–70% yields in the absence of a transition metal.
