Amide Synthesis through the In Situ Generation of Chloro- and Imido-Phosphonium Salts. [PDF]
We describe a methodology for the amidation of carboxylic acids by generating phosphonium salts in situ from N-chlorophthalimide and triphenylphosphine. Aliphatic, benzylic, and aromatic carboxylic acids can be transformed into their amide counter parts ...

Biological and structural studies of phosphonium 'masked thiolate' compounds [PDF]
The ability of phosphonium cations to act as intracellular transport vectors is well-established. Phosphonioalkylthiosulfate zwitterions, and (omega)-thioacetylalkylphosphonium salts, which act as 'masked thiolate' ligands, are useful precursors for the ...

Trypanocidal action of bisphosphonium salts through a mitochondrial target in bloodstream form Trypanosoma brucei [PDF]
Lipophilic bisphosphonium salts are among the most promising antiprotozoal leads currently under investigation. As part of their preclinical evaluation we here report on their mode of action against African trypanosomes, the etiological agents of ...

Synthesis of stereodefined 1-aryl(heteroaryl) substituted 1,2-bis(2-bromopyridin-3-yl)ethenes by selective tandem Suzuki-Miyaura Cross-coupling reactions [PDF]
In this communication we show the preparation of stereodefined trisubstituted alkenes 2 can be achieved by sequential selective Suzuki-Miyaura reactions of 2-bromo-3-(2,2-dibromovinyl)pyridines.

Remarkable cage deboronation and rearrangement of a closo-1,12-dicarbadodecaborane to form a neutral nido-7,9-dicarbaundecaborane. [PDF]
Deboronation and cage rearrangement of the closo-1,12-carborane salt [1,12-(PPh2Me)2-1,12-C2B10H10]I2 occurs in refluxing methanol to give the zwitterionic nido-7,9-carborane 7,9-(PPh2Me)2-7,9-C2B9H9.
