As a continuation of our earlier systematic study, this paper reports on the performance of boron polypodands 1–8 (B-podands) as catalysts in a series of anion promoted reactions (nucleophilic substitution, reduction, N- and O-alkylation) in chlorobenzene, toluene and acetonitrile solutions carried out in the solid–liquid (SL) phase transfer catalysis (PTC) conditions. Comparison of the catalytic efficiency (expressed by observed rate constants) of 1–8 with that of well known classical phase transfer catalysts: crown ethers, polyethylene glycols (PEG) (9, 10) and previously studied Si-podands (11, 12) is also included.
We have reported the systematic study on the use of boron polypodands (B-podands) as catalyst in a series of anion promoted reactions (nucleophilic substitution, reduction, N- and O-alkylation) in chlorobenzene, toluene and acetonitrile solutions carried out under solid–liquid (SL) phase transfer catalysis (PTC) conditions.Figure optionsDownload as PowerPoint slide
