✦ Synopsis

The effect of sulfone structure (phenyl vs t-butyl) is compared in the conjugateaddition reactions of ortho substituted and ortho, ortho disubstituted aryl lithium reagents -with y-silyloxy-a,@-unsaturated sulfones.

Our earlier reports on the use of y-oxido-a,B-unsaturated sulfones (& n=5,6,7
