Personal care formulation

A method of preparing an acryloxy-functional organosilicon compound is provided. The method comprises reacting (A) an initial organosilicon compound and (B) an acrylate compound in the presence of (C) a catalyst. The initial organosilicon compound (A) has one alcohol functional group (i.e., is monohydroxyl functional). The catalyst (C) has the formula M[RC(O)CHC(O)R], where M is a group IV transition metal and each R is an independently selected substituted or unsubstituted hydrocarbyl group. An acryloxy-functional organosilicon compound prepared by the method is also provided. The acryloxy-functional organosilicon compound is prepared in increased purity, without relying on toxic catalysts.

Method of preparing acryloxy-functional organosilicon compounds

Polyethers are prepared by polymerizing an alkylene oxide in the presence of a double metal cyanide catalyst complex and certain Mmetal or semi-metal compounds. The double metal cyanide catalyst complex contains 0.5 to 2 weight percent potassium. The ability of this catalyst system to tolerate such high amounts of potassium permits the catalyst preparation procedure to be simplified and less expensive.

Improved methods of synthesizing 6-aryl-4-aminopicolinates, such as arylalkyl and alkyl 4-amino-3-chloro-6-(4-chloro-2-fluoro-3-methoxyphenyl)pyridine-2-carboxylates and arylalkyl and alkyl 4-amino-3-chloro-5-fluoro-6-(4-chloro-2-fluoro-3-methoxyphenyl)pyridine-2-carboxylates, are described herein. The improved methods include a direct Suzuki coupling step, which eliminates the protection/de-protection steps in the current chemical process, and therefore eliminates or reduces various raw materials, equipment and cycle time as well as modification of other process conditions including use of crude AP, use of ABA-diMe, and varying pH, catalyst concentration, solvent composition, and/or workup procedures. This includes synthesis of 2-aryl-6-aminopyrimidine-4-carboxylates.
