Abstract

Abstract. Essentially complete fission of the PP bonds in red phosphorus can be effected by adding one equivalent of t-butylalcohol to a mixture of red P and lithium in liquid ammonia. The reaction has been applied to synthesize some dialkylphosphanes. ... Russian investigators [l] (compare [2]) reported on the reaction of red phosphorus with sodium in liquid ammo- nia and subsequent alkylation, affording tetraalkyldiphos- phanes R,P-PR, in - 25% yield and small amounts ...
