Chiral aryl methyl sulfoxides proved to be efficient activators in the asymmetric allylation of aldehydes with allyl trichlorosilanes. High enantioselectivity was found in the case of electron-poor aldehydes. The high levels of diastereoselectivity and the detection of nonlinear effects have allowed the elucidation of some mechanistic aspects of the reaction.

Metal-containing Schiff base/sulfoxides were developed as chiral ligands for Pd(II)-catalyzed asymmetric intramolecular allylic C–H amination reactions. The use of metal-containing base allows tuning the selectivity and reactivity Pd(II)-catalyst, whereby a base-Cu(II)/sulfoxide ligand in combination with Pd(OAc)2 showed best performance. Both internal terminal alkenes applicable, products obta...

ion (Figure 4). Such products, of course, are a matter of speculation before the experiment. The results of these photolyses, presented in Table 1, do not include any of the speculative products in Figure 4. Benzaldehyde was a minor product observed for photolysis of 4 (in acetone), 6, and 8 and is not accounted for by either Figure 2 or Figure 4. All of the compounds for which PhCHO is observe...
