Here, we report the selective, catalytic isomerization of cis-1,2-diols to trans-diequatorial-1,2-diols. The method employs triphenylsilanethiol (Ph3SiSH) as a catalyst and proceeds under mild conditions in the presence of a photoredox catalyst and under

Palladium-catalyzed cross-coupling of hypervalent arylsiloxane derivatives proceeded in good to excellent yields with allylic benzoates. Arylation occurred with complete inversion of configuration. The scope and limitations of this reaction, an alternative to the Stille coupling, is summarized.

The stable, readily available molybdenum(II) complexes [Mo(CO)4Br2]2 (B) and Mo(CO)3(MeCN)2-(SnCl3)Cl (C) have been found to catalyze C-C bond- forming allylic substitution with electronrich aromatics (e.g., 15 + PhOMe → 62) and heteroaromatics (e.g., 15 + 36 → 88) as nucleophiles under mild conditions (room temperature, 30 min-3 h). Remarkable is the para-selectivity for anisole, whereas phenol tends to favor ortho-substitution in certain instances. Mechanistic and stereochemical experiments are indicative of Lewis-acid catalysis rather than a metal template-controlled process.

The tin(IV) chloride promoted coupling reaction of allylstannanes with various arenes proceeded to give the allylated arenes in good yields.It was also found that tin(II) bromide was an effective catalyst for Friedel-Crafts allylation using allylic bromid
