Usage

General Description

Dimethallyl ether is a chemical compound with the formula C6H10O that is used in the production of polymers and resins. It is a colorless liquid with a pungent odor and is highly flammable. Dimethallyl ether is commonly used as a comonomer in the production of various copolymers, which are used in the manufacturing of coatings, adhesives, and sealants. It is also used as a crosslinking agent in the production of thermosetting resins, which are used in the production of plastics and other composite materials. Due to its flammability and potential health hazards, dimethallyl ether should be handled and stored with care in a well-ventilated area and appropriate personal protective equipment should be worn when working with this chemical.

Halide-Free Dehydrative Allylation Using Allylic Alcohols Promoted by a Palladium-Triphenyl Phosphite Catalyst

The triphenyl phosphite-palladium complex was found to effect catalytic substitution reactions of allylic alcohols via a direct C-O bond cleavage. The dehydrative etherification proceeded efficiently without any cocatalysts and bases to give allylic ethers in good to excellent yields.

Process for the production of organosilicon compounds

Organosilicon compounds of the formula STR1 wherein R1 and R2 are each independently straight or branched alkyl of 1 to 4 carbon atoms or --OR3, R3 is R4 --(OR5)m --, R6 is straight or branched alkyl of 1 to 4 carbon atoms, m is an integer from 0 to 6, inclusive, R5 is straight or branched alkylene of 2 to 4 carbon atoms, which may be identical or different when m is an integer from 2 to 6, and R6 is straight or branched alkylene of 2 to 6 carbon atoms, are prepared by reacting hydrogensilanes of the formula STR2 wherein R7 are identical or different groups R4 or the group OR4, and R4 has the previously indicated meaning, with terminally unsaturated ethers of the formula wherein m, R4 and R5 have the previously indicated meanings, and R8 is terminally unsaturated straight or branched alkenyl or 2 to 6 carbon atoms, in the presence of a catalyst at controlled temperatures to form addition products of the formula STR3 wherein m and R4, R5, R6 and R7 have the previously indicated meanings, and the R4 's are identical or different which are converted into the desired end products by thermal and/or catalytic transesterification with monofunctional hydroxy compounds of the formula wherein m, R4 and R5 have the previously indicated meanings.
