A Convenient Route for Monodealkylation of Diethyl Phosphonates
摘要:
Lithium bromide and lithium chloride have been found to cause monodealkylation of diethyl phosphonates resulting in formation of ethyl lithium phosphonates in high yields.

Dicyclohexylammonium 2-diethylphosphonoacrylate reacts readily with a variety of 1,3-dicarbonyl and monocarbonyl pronucleophiles to give the corresponding Michael adducts. Self-catalysis in these reactions is postulated.
