Abstract
![]()
The metal-free reduction
of a range of phosphine(V) oxides employing
oxalyl chloride as an activating agent and hexachlorodisilane as reducing
reagent has been achieved under mild reaction conditions. The method
was successfully applied to the reduction of industrial waste byproduct
triphenylphosphine(V) oxide, closing the phosphorus cycle to cleanly
regenerate triphenylphosphine(III). Mechanistic studies and quantum
chemical calculations support the attack of the dissociated chloride
anion of intermediated phosphonium salt at the silicon of the disilane
as the rate-limiting step for deprotection. The exquisite purity of
the resultant phosphine(III) ligands after the simple removal of volatiles
under reduced pressure circumvents laborious purification prior to
metalation and has permitted the facile formation of important transition
metal catalysts.

Abstract
A series of 1-substituted-3-methyl-2-phospholene oxides was prepared from the corresponding 3-phospholene oxides by double bond rearrangement. The 2-phospholene oxides could be obtained by heating the 3-phospholene oxides in methanesulfonic acid, or via the formation of cyclic chlorophosphonium salts. Whereas mixtures of the 2- and 3-phospholene oxides formed, when the isomerization of 3-phospholene oxides was attempted under thermal conditions, or in the presence of a base. The mechanisms of the various double bond migration pathways were elucidated by quantum chemical calculations.
