Vinyltetrazoles: III. Metal-catalyzed arylation, a new method of vinyltetrazoles functionalization
摘要:
New functionalization procedure was developed for C- and N-vinyltetrazoles based on Heck reaction. Applying this method diverse (E)-styryl- and (E)-distyryltetrazoles were obtained for the first time in 76-85% yields. C-Vinyltetrazoles are more reactive in Heck cross-coupling than N-vinyltetrazoles. The arylation of 1-vinyltetrazole along Heck reaction proceeds with a C-H-activation and leads to the formation of 5-phenyl-1-[2-(E)-phenylethenyl]tetrazole.

Microwave-assisted Heck arylation of C- and N-vinyltetrazoles has been accomplished for the first time. Microwave irradiation has been shown to considerably promote the arylation of tetrazoles.
