Reaction of (PPh3)2C→CO2 with halogenated hydrocarbons; Formation and crystal structure of a cationic ester with 1, 2-dichloroethane

The carbodiphosphorane CO2 adduct (2) reacts slowly with 1, 2-dichloroethane to give (HC{PPh3}2)Cl (5) as result of HCl abstraction along with the ester-like salt (ClCH2CH 2O(O)CC{PPh3}2)Cl (4) from nucleophilic substitution of one Cl- by 2. Both compounds could be separated by fractional crystallization. Attempts to dissolve 2 in 1, 2-difluorobenzene leads to small amounts of the hydrolysis product (HC{PPh3} 2)(HCO3)·H2O (6·H2O) caused by some humidity in the solvent. All compounds could be crystallized and the structures studied by X-ray analyses and 31P NMR spectroscopy. Copyright
