Cobalt-Catalyzed syn Hydrophosphination of Alkynes. — Thiophosphinyl deriva(III), (VI), (VIII), and (XI) are formed as major or exclusive products with com35- 199 tives
plete (E)-selectivity. The primary adducts are converted to phosphane sulfides to clarify
the efficiency of the hydrophosphination reaction. Free phosphane (XV) is relatively
insensitive to oxygen and can be isolated. Its conversion to an ylide and application to
Wittig reactions demonstrates the utility of the products of hydrophosphination. —
