Chlorodiphenylphosphine → HCID 178420371, compound

Participants

Reaction Steps

Procedure as described for NP Amidine XVII using the following amounts: 3.06 g of N1-(thiazol-2-yl)benzamidine (Amidine XVI, 15.0 mmol), 7.50 mL of 2.0 M butyllithium (15.0 mmol), 0.93 mL of chlorodiphenylphosphine (15.0 mmol). Following removal of lithium chloride, the solvent was removed from the filtrate to give a sticky residue. The sticky residue was suspended in 100 mL of pentane. Vigorous stirring and scraping eventually yielded an off-white solid after 2 hours. The solid was collected and dried (2.59 g). The lithium chloride solid separated from reaction solution was extracted with 100 mL of diethylether, filtered, taken to dryness, and treated with 100 mL of pentane. Stirring and scraping produced white solid that was collected and dried yielding an additional 1.56 g of solid. Combined yield 4.15 g (71%).
