Tetrabutylammonium tetrakis borate

FIG. 6 Typical cyclic voltammogram obtained for the transfer of pilocarpine hydrochloride at the water-DCE interface. The organic phase contains 0.01 M tetrabutylammonium tetrakis(4-chloro-phenyl)borate, the aqueous solution is 0.01 M HCl + 0.2 mM pilocarpine hydrochloride, and the sweep rate is fixed at 10, 25, 75, 100, and 150mV/s.

Oxygen Nucleophile. Uchiro et al. have reported hydrolysis of a thioglycoside bond under very mild conditions using the combination of tetrabutylammonium periodate as oxidant, trityl tetrakis(pentafluorophenyl)borate as Lewis acid catalyst, and HMDO in anhydrous acetonitrile at 0 °C (eq 17). The reaction also proceeded well in the absence of HMDO, using aqueous tri-flic or perchloric acid as catalyst in place of the trityl derivative. The intersaccharidic bond of a disaccharide was found to be stable under these conditions, with no anomerization being observed.
