Summary: Aryldiazonium tetrafluoroborates react with allylsilanes to yield allylazo compounds. If the allylic carbon attached to the azo group carries hydrogen, tau- tomerization with formation of hydrazones takes place. ... The coupling of aryldiazonium ions with arylamines and phenols, discovered by Griess in 1858; has been one of the most important reactions in industrial chemistry for more than a century.2 Among the aliphatic C-nucleophiles ...
