aliphatic sulfamates and related derivatives incorporating cyclic/polycyclic (steroidal) moieties in their molecules has been synthesized and assayed as inhibitors of the zinc enzyme carbonic anhydrase (CA) and, more precisely, of the cytosolic isozymes CA I and II and the transmembrane, tumor-associated isozyme CA IX. The most potent CA I inhibitor was n-tetradecyl sulfamate and some (substituted)benzyl/phenethyl

Predicting site selectivity in C–H bond oxidation reactions involving heteroatom transfer is challenged by the small energetic differences between disparate bond types and the subtle interplay of steric and electronic effects that influence reactivity. Herein, the factorsgoverningselective Rh2(esp)2-catalyzed C–H amination of isoamylbenzene derivatives are investigated, where modification to both

To provide a method for producing a phosphoryl imide salt represented by the following general formula (1) at a satisfactory yield by cation exchange. The method comprises the step of performing cation exchange by bringing a phosphoryl imide salt represented by the following general formula (2) into contact with a cation exchange resin having M

or a metal salt represented by the general formula (4) in an organic solvent having a water content of 0.3% by mass or less.
A novel hetergeneous mercury salt catalyst stabilized by m-carbaborane can be used and reused for various chemical reactions without leaching the metal.
