2-Chloro-5,5-dimethyl-1,3,2-dioxaphosphorinane 2-oxide

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A 100 mL round bottom flask equipped with a stirrer bar was charged with 15.04 g (0.134 mol) 3-cyclohexene-1-methanol, 22.52 g (0.122 mol) of 2-chloro-5,5-dimethyl-1,3,2-dioxaphosphorinan-2-one, and 10.6 g (0.134 mol) of pyridine. After the above mixture was reacted at 80° C. for 3 hrs. The reaction mixture was added to chloroform (100 mL), and then washed with chloroform (2×100 mL), dried with sodium sulfate. The solvent was evaporated and the residue distilled to give pure product.
