摘要：
7-Bromo-3-methyl-[1,2,3]triazolo[1,5- a] pyridine 1 at 1.7 atm and 100 degrees C decompose to form a pyridylcarbene intermediate by nitrogen expulsion. The carbene stabilization give 2-bromo-6-vinylpyridine 2, 1-(6-bromopyridin-2-yl) ethanol 3, 1-(6-Bromopyridin-2-yl) ethanone 4, 2bromo- 6-[ 2-( 6- bromopyridin- 2- yl)- 2- methyl- trans- cyclopropyl] pyridine 5, and 2- bromo- 6-[ 2-( 6bromopyridin-2-yl)-2-methyl-cis-cyclopropyl] pyridine 6.
