Synthesis of carborane-containing phosphates by catalytic phosphorylation
摘要:
The catalytic phosphorylation of o-carboranylmethanol with different phosphorus acid chlorides has been studied. This method makes it possible to obtain esters of phosphorus acids and esters of the corresponding phosphorus acid chlorides containing carboranylmethyl groups. The catalytic phosphorylation of 1,2-bis(hydroxymethyl)-o-carborane affords both acyclic and cyclic phosphate esters. The structure of the synthesized o-carborano[1,2-e]-1,3,2-dioxaphosphepane was confirmed by X-ray diffraction analysis.
