摘要

Abstract: By use of the technique of laser flash photolysis, rate constants k,, and ks have been directly measured for the reactions at 20 OC in acetonitrileTwater (AN-W) solutions of varying composition of 18 triarylmethyl and 10 diarylmethyl cations with azide and solvent. The cations have ks that depend on substituent and vary from-10'to-IO7 sl. For the more stable ions kk also varies, increasing with decreased electron donation and also ...
