Routes to compounds with one or more t-butyl groups directly attached to phosphorus have been explored, and a number of new compounds of this type have been prepared. Reduction of t-butylphosphonothioic dichloride with triphenylphosphine provides a route to t- butylphosphonous dichloride which, although having more stages than that previously described, may be advantageous for large scale operation. The Arbusov reaction and ...
