Transition-Metal-Free and Base-Promoted Carbon-Heteroatom Bond Formation via C-N Cleavage of Benzyl Ammonium Salts

A facile and general method for constructing carbon-heteroatom (C-P, C-O, C-S, and C-N) bonds via C-N cleavage of benzyl ammonium salts under transition-metal-free conditions was reported. The combination of t-BuOK and 18-crown-6 enabled a wide range of substituted benzyl ammonium salts to couple readily with different kinds of heteroatom nucleophiles, i.e. hydrogen phosphoryl compounds, alcohols, thiols, and amines. Good functional group tolerance was demonstrated. The scale-up reaction and one-pot synthesis were also successfully performed.

Palladium-catalyzed C(sp3)–P(III) bond formation reaction with acylphosphines as phosphorus source

Palladium-catalyzed C(sp3)–P(III) bond formation reaction for alkyl substituted phosphines preparation was developed. In this reaction, various alkyl bromides and limited alkyl chlorides reacted with acylphosphine under relative mild and easily accessible condition, and differential phosphines were afforded in good yields. This reaction made up the application of palladium catalysis in C(sp3)–P(III) bond formation, and indicated a practical application of acylphosphine as a phosphination reagent.

Controllable phosphorylation of thioesters: Selective synthesis of aryl and benzyl phosphoryl compounds

The controllable phosphorylations of thioesters were developed. When the reaction was catalyzed by a palladium catalyst, aryl or alkenyl phosphoryl compounds were generated through decarbonylative coupling, while the benzyl phosphoryl compounds were produced through deoxygenative coupling when the reaction was carried out in the presence of only a base.

Sodium exhibits better efficacy and selectivity than Li and K for converting Ph3P(O) to Ph2P(OM). The destiny of PhNa co-generated is disclosed. A series of alkyl halides R4X and aryl halides ArX all react with Ph2P(ONa) to produce the corresponding phosphine oxides in good to excellent yields.

An ambident electrophilicity of phosphinic acid thioesters is disclosed. Unexpected carbon-sulfur bond formation took place in the reaction between phosphinic acid thioesters and benzyl Grignard reagents. The developed method for benzyl sulfides has a wide substrate scope and was applicable for the synthesis of a drug analog.

A palladium-catalyzed phosphorylation of benzyl ammonium triflates with P(O)H compounds has been developed. Various benzylphosphorus compounds were produced in good to excellent yields with high functional group tolerance. All the three kinds of hydrogen phosphoryl compounds, i.e. H-phosphonates, H-phosphinates and secondary phosphine oxides, were applicable to this reaction. The successful scale-up experiment and one-pot synthetic operation also well demonstrated its practicality.

Copper-catalyzed C–P cross-coupling of arylmethyl quaternary ammonium salts via C–N bond cleavage

Arylmethyl quaternary ammonium salts with various functional groups and a variety of dialkyl- and diarylphosphine oxides afford C–P cross-coupling products with good yields. This protocol requires no inert atmosphere, no ligand, and simple operation steps. Graphic abstract: [Figure not available: see fulltext.].
