摘要

Two problems have hindered the Gomberg-Bachmann (GB) and Pschorr reactions of arenediazonium cations: the instability of the arenediazonium salts and side reactions. Arenediazonium tetrafluoroborate and hexafluorophosphate salts can be prepared in high yield and purity and can be stored safely. Unfortunately, these salts are insoluble in most nonpolar organic solvents. Crown ether complexation or other phase-transfer (pt) catalytic ...
