Selected examples of a vanadium-catalyzed SOS reaction ^a

Entry	R	R′	R″	Yield b
a c	−C6H13	H	H	70%
b		H	H	75%
c		H	H	84%
dd		H	H	66%
e		H	H	65%

^aAll reactions unless otherwise noted were performed at 0.3 M concentration of substrate using 1.2 eq. tributylphosphine to quench the selenenate intermediate.

^bAll yields are isolated yields after chromatography over silica gel.

^cThis reaction was quenched with triphenyl-phosphine.

^dt-Butyl hydroperoxide was substituted for cumene hydroperoxide to simplify purification.
