A novel and facile copper-catalyzed synthetic methodology was developed to access a large variety of 4-phosphoryl-substituted 1naphthylamines by reacting various 1-naphthylamines with different diarylphosphine oxides in the presence of Cu(OAc) 2 and Ag 2 CO 3 in one pot under mild reaction conditions. This copper-catalyzed synthetic system was also suitable for being employed to synthesize 4-trifluoromethylsubstituted 1-naphthylamines by reacting various 1-naphthylamines with Togni's reagent in the presence of CuI and NaOAc in DMSO in one pot under mild reaction conditions.

An efficient one-pot green strategy hasb een developed for the synthesiso fb-ketosulfones by directly using easily availableand inexpensive sulfonyl chlorides as as ulfur source to react with aromatic alkenes in the presence of cheap tert-butyl hydroperoxide (TBHP) and Et 3 Ni n 1,2-dichloroethane (DCE) at 45 8Cwithin 3h.Scheme1.Comparision of previousw ork with this study.

A novel multiheteroatom (N, O and P) [3,3]-sigmatropic rearrangement is disclosed, based on two important types of organophosphates, 2-(N-heteroaryl) methyl phosphates and α-keto phosphates, being accessed smoothly and efficiently.

Using tert‐butyl hydroperoxide as the oxidant, alkyl/aryl‐sulfonyl chlorides (I) react with vinyl(het)arenes (II) and (IV) to the corresponding (het)aryloylmethyl alkyl/aryl sulfones.
