摘要: Abstract Cyclopalladation of 2-tert-butyl-4,4-dimethyl-2-oxazoline (1) using Pd(OAc)2 was performed in acetic acid and on silica gel. Treatment the crude product formed each reaction with LiCl afforded a dimeric cyclopalladated complex (4) 76 93% yield, respectively. The 1H, 13C{1H} NMR IR spectroscopy data for 4 confirmed formation palladacycle an (sp3)C–Pd bond suggested presence two geometrical isomers solution.
