Sažetak

BH3cN- has been found to be a moderately efficient trapping
agent for triphenylmethyl cations, roughly comparable to chloride
ion. Since BH3CN- is moderately resistant to acid hydrolysis, it can
trap triphenylmethyl cations generated by treatment of triphenylcarbinol
with HCl in 25% water - 750/o tetrahydrofuran. A quantitative
yield of triphenylmetharie, based on unrecovered tripheny~carbinol,
can be obtained, but the process is inefficient in its use of
BH3CN- because of the competing hydrolysis.
