Conclusions
-
1.
A number of esters of carboranylphosphonous and carboranylphosphonic acids was obtained.
-
2.
The esters of carboranylphosphonous acids are capable of entering into the Arbuzov reaction under the influence of various electrophilic reagents.
-
3.
The C-P bond is cleaved when carboranylphosphonites are reacted with water and alcohols.
-
4.
The presence of the electron-acceptor carboranyl group on the phosphorus atom is reflected in a certain decrease in the reactivity of the carboranylphosphonites.
