In an embodiment, the alkylene carbonate is further transesterified with the alcohol to produce a dialkyl carbonate and an alkylene glycol.

Alkylene carbonates and optionally dialkyl carbonates are prepared by reaction of an alkylene oxide with carbon dioxide in the presence of an alcohol.

The compounds can be prepared by reacting a halogenoalkanephosphonic acid compound with an alkylene di- or polyamine followed by guanidation of the so obtained product.

The invention relates to enzymatic methods for epoxidation of a non-cyclicaliphatic alken, or a terpen.

Migratory insertion of an alkene into a metal hydride.

The recurring 1-alkene units of the copolymer have a branch ratio of less than 0.19, indicative of a poly 1-alkene segment of the copolymer chain or backbone that is essentially linear.

This reaction proceeds easily in an alkaline medium.

Once isolated, the functionalized alkene intermediate can be self-metathesized or cross-metathesized (e.g., with a second functionalized alkene) to produce the desired organic compound or a precursor thereto.

A catalyst composition for dehydration of an alcohol to prepare an alkene is provided.

A hydrosilation catalyst comprises a platinum-alkene complex bound to a polymer support.

The presence of the alkene in the alkene-to-aldehyde reaction can enhance the efficiency of the processes.

The present invention relates to a catalytic composition for producing a 1 -alkene-acrylate copolymer that includes a metal nano catalyst, and a method for producing a 1-alkene-acrylate copolymer.

This product is then reacted with an aldehyde, ketone, imine or alkene.

A sample of ambient air is heated to convert any alkyl ester of phosphoric acid to an alkene.

An alkene interpolymer is prepared by polymerizing at least one 3-substituted C4-10 alkene and at least one C2-8 alkene in a gas phase polymerization using a polymerization catalyst system.
