Preparation of BIS(o- and m-carboranyl) disulfides by reaction of sulfur chlorides with o- and m-carboranes in presence of A1C13

1. A simple method was proposed for obtaining the bis(9-o- and 9-m-carboranyl) disulfides from the o- and m-carboranes and S2C12 in the presence of A1C13, and also a simple method for reducing the latter to the 9-o- and 9-m-carboranylthiols. 2. When the o- and m-carboranes are reacted with SC12 in the presence of A1C13 the main products are the bis (o- and m-carboranyl) disulfides.
