this transition-metal-free reaction, DMSO acts as not only a solvent but also a "S(O)Me" source, thus providing a convenient method for the efficient and direct synthesis of various benzyl methyl sulfoxides.
(RR-1), recognized p-halobenzyl methylsulfoxides with high R-enantioselectivity (86–99% ee) to form inclusion compounds. The single-crystal X-ray analyses showed that RR-1 molecules are arranged in parallel and zigzags via hydrogen bonding to construct a pleated sheet. The guest molecules that form hydrogen bond with +NH3 of RR-1 are accommodated in the channel cavity between the layers. In contrast to
