چکیده
Both C-Cl bonds of CH(2)Cl(2) are readily activated by CoCl(2) and metallic Zn allowing quantitative methylation of phosphines; unprecedented zwitterionic Co(ii) and Zn(ii) intermediates have been characterized which display alpha-metallated phosphoniums.

Tracking reactive intermediates in phosphine-promoted reactions with ambiphilic phosphino-boranes.
The ambiphilic phosphino-borane i-Pr2P(o-C6H4)BMes2 affords stable versions of key zwitterionic intermediates by reactions with diethyl azodicarboxylate or PhNCO.
متن کاملRational design of novel ligands for environmentally benign cross-coupling reactions*
Transition-metal (TM) complexes of new phosphines, readily prepared by a straight forward three-step modular synthesis, were successfully employed in difficult crosscoupling reactions conducted under mild conditions (water, “open-flask”, low temperature) that aspire to meet green chemistry criteria. High yielding catalyzed by bismuth or rhodium complexes oxidative arylation of naphthoquinone ga...
متن کاملAn experimental and theoretical study into the facile, homogenous (N-heterocyclic carbene)2-Pd(0) catalyzed diboration of internal and terminal alkynes
PdIJITMe)2(PhCCPh) acts as a highly reactive pre-catalyst in the unprecedented homogenous catalyzed diboration of terminal and internal alkynes, yielding a number of novel and known syn-1,2-diborylalkenes in a 100% stereoselective manner. DFT calculations suggest that a similar reaction pathway to that proposed for platinum phosphine analogues is followed, and that destabilization of key inter...
متن کاملPhosphonium Formation by Facile Carbon-Phosphorus Reductive Elimination from Gold(III).
A recent trend in homogeneous gold catalysis has been the development of oxidative transformations relying on Au(I)/Au(III) redox cycling. Typically, phosphine-supported Au(I) precatalysts are used in the presence of strong oxidants to presumably generate phosphine Au(III) intermediates. Herein, we disclose that such Au(III) complexes can undergo facile C(aryl)-P reductive elimination to afford...

Triphenyl phosphine(PPh3), an efficient and reusable catalyst, catalysed the synthesis of 2-amino-3-cyano-6-methyl-4-aryl-4H-pyran-5-ethylcarboxylate derivatives by one-pot condensation of aromatic aldehydes, malononitrile and ethyl acetoacetate in EtOH-H2O (1:1) at reflux conditions. The results show that ...
