Dimethyl chlorophosphite

Dimethyl chlorophosphite, (CH30)2PC1 (1). This dimethyl ester of phosphoro-chloridous acid is obtained by reaction of (CH30)3P with PC13 in [(CH3)2N]3PO as solvent (74.5% yield).1... [Pg.146]

The phosphorylation of potassiopyrrole by the chlorides of phosphorous acid shows [21] that the process is selective and leads to the products from N-phosphorylation. The reaction of 2,4-dimethyl- and 2,3,5-trimethylpyrroles with chlorophosphites makes it possible to obtain mono- and diphosphorylated alkylpyrroles, depending on the ratio of the phosphorylating agent and alkylpyrrole [22, 23]. [Pg.3]

Hofmann used a triptycene type backbone for preparing diphosphite 145, in overall 40% yield from three steps, starting from a conveniently substituted anthracene. Reaction of the substituted anthracene with dimethyl fumarate under microwave irradiation considerably reduced reaction time to prepare the triptycene derivative. After deprotection, the corresponding diol was then treated with chlorophosphite to give 145. The ligand was used in theoretical studies on rhodium(i)-catalysed hydroformylation of butadiene. The same authors also prepared iridium complex 146, from the already known diphosphite, which was used for the same purpose. [Pg.90]
