摘要： A titanium catalyst for reaction between a compound having a carbon-carbon unsaturated bond and a compound having an electrophilic functional group or an electrophilic reagent, said titanium catalyst being composed of a titanium compound represented by the formula (1) below TiX1X2X3X4 (1) (where X1, X2, X3, and X4 denote independently a halogen atom, C1-20 alkoxyl group, aralkyloxy group, aryloxy group, or —NRxRy group (where Rx and Ry denote independently a C1-20 alkyl group or aralkyl group), and any two of X1, X2, X3, and X4 may form a ring.) and a Grignard reagent represented by the formula (2) below in a molar amount 1.5-2.5 times as much as the titanium compound. R1MgX5 (2) (where R1 denotes a C2-10 alkyl group having a hydrogen atom at the β position and X5 denotes a halogen atom.) The titanium catalyst of the present invention activates the carbon-carbon unsaturated bond, which has a comparatively low reactivity, thereby catalyzing the reaction with an electrophilic functional group. It is inexpensive and industrially advantageous. When applied to reaction between a compound having a carbon-carbon unsaturated bond and an electrophilic functional group, it yields industrially a variety of adducts of a compound having a carbon-carbon unsaturated bond and a compound having an electrophilic functional group, and it also yields a variety of intramolecular adducts of a compound having a carbon-carbon unsaturated bond and an electrophilic functional group in the same molecule.

The chlorinated alkenes can be easily hydrolyzed to provide .alpha.-monochloroketones or .alpha.,.alpha.-dichloroketones with a high degree of selectivity. The resulting .alpha.-monochloroketones or .alpha.,.alpha.-dichloroketones have utility as fungicides or function as useful intermediates for fungicides.

摘要： A process and catalyst for Shape Selective Hydrocarbon Conversions such as the regioselective disproportionation of toluene to para-xylene wherein hydrocarbon to be converted is passed over a catalytic molecular sieve which is trim selectivated with a reaction stream comprising toluene and a silicon-containing high efficiency p-xylene selectivating agent under toluene conversion conditions. The toluene disproportionation process attains a single-pass para-xylene product over 95% coupled with a toluene conversion of at least 15%. The present invention also includes the highly para-selective catalyst which results from the treatment of a catalytic molecular sieve with a high efficiency p-xylene selectivating agent under the recited conditions.
