Abstract

Deboronation and cage rearrangement of the closo-1,12-carborane salt [1,12-(PPh2Me)2-1,12-C2B10H10]I2 occurs in refluxing methanol to give the zwitterionic nido-7,9-carborane 7,9-(PPh2Me)2-7,9-C2B9H9. Notably, deboronation and cage substitution of the isomeric closo-1,7-carborane salt [1,7-(PPh2Me)2-1,7-C2B10H10]I2 takes place in methanol to afford the salt [10-OMe-7,9-(PPh2Me)2-7,9-C2B9H9]I.
