Effects of structural factors in silyl ethers derived from terminal acetylenic alcohols on 1,4-O-->C-sp migration of the silyl group in the Iotsitch reagent were studied. The effect of steric factor at the carbon atom neighboring to the reaction center was found to be stronger than that at the silicon atom in the migrating group.

inexpensive, nontoxic manganese catalyst enabled unprecedented redox‐neutral carbonylative annulations under ambient pressure. The manganese catalyst outperformed all other typically used base and precious‐metal catalysts. The outstanding versatility of the manganese catalysis manifold was reflected by ample substrate scope, setting the stage for effective late‐stage manipulations under racemization‐free

1,2-disubstituted heterocyclic compounds which are inhibitors of phosphodiesterase 10 are described. Also described are processes, pharmaceutical compositions, pharmaceutical preparations and pharmaceutical use of the compounds in the treatment of mammals, including human(s) for central nervous system (CNS) disorders and other disorders which may affect CNS function. Among the disorders which may be treated are neurological, neurodegenerative and psychiatric disorders including, but not limited to, those associated with cognitive deficits or schizophrenic symptoms.
