Cerium chloride

A particularly useful reaction has been the selective 1,2-reduction of a, P-unsaturated carbonyl compounds to aHyUc alcohols, accompHshed by NaBH ia the presence of lanthanide haUdes, especially cerium chloride. Initially appHed to ketones (33), it has been broadened to aldehydes (34) and acid chlorides (35). NaBH by itself gives mixtures of the saturated and unsaturated alcohols. [Pg.304]

Elemental composition Ce 56.85%, Cl 43.15%. In the aqueous phase following acid digestion, cerium may he analyzed by various instrumental techniques (see Cerium). Chloride ion in the solution may be measured by ion chromatography, chloride ion-selective electrode or titration with silver nitrate using potassium chromate indicator. The solution may require appropriate dilution for analysis of both the metal and the chloride anion. [Pg.202]

Addition of 2,6-dimethoxypyrimidine-4-cerium chloride 371 to the chiral lactone 370 occurred without racemization of the chiral center, and the product 372 was subsequently used in a successful total synthesis of (—)-7-epicylindro-spermopsin <2002JA4950, 2005JOC1963>. The cerium reagent was prepared situ from 4-bromo-2,6-dimeth-oxypyrimidine by sequential addition of butyllithium and cerium trichloride. Addition of the same dimethoxypyrimidine-4-cerium derivative to a chiral lactam has also been reported <1999J(P1)1193>. [Pg.166]

In this current work, cerium-modified MCM-41 mesoporous molecular sieve was synthesized using heptahydrated cerium chloride, colloidal fumed-silica, sodium hydroxide, cethyltrimethylammonium bromide and water. The incorporation of cerium to MCM-41 improved the quality, stability and acid properties of the resulting ordered mesoporous material. Its surface and structural properties were extensively studied by nitrogen adsorption and high-resolution thermogravimetry. [Pg.188]
