    Abstract: Polyether polyols, derivatives and combinations thereof are converted to olefins under reductive or non-reductive dehydroxylation conditions, in the presence of a halogen-based catalyst. Derivatives include polyether polyols incorporated in polyurethanes. The process includes gas pressure from 1 psig (~6.89 KPa) to 2000 psig (~13.79 MPa), a temperature from 50 °C to 250 °C, a liquid reaction medium, and a molar ratio of the starting material to halogen atoms from 1:10 to 100:1.

    Abstract: A process for preparing an alkyl alkanoate, comprising contacting a an alkene, carbon monoxide (CO), an alcohol, a catalyst and a co-catalyst comprising a Bronsted acid, under alkoxycarbonylation conditions to produce an alkyl alkanoate, wherein the catalyst comprises a metal-organophosphorous ligand complex comprising a ligand of the following formula: wherein X1 – X8 are independently, H, R, Ar, substituted Ar, OR, OAr, CO2R, SiR3, SO3R, SO3H, or fluoro; where R is alkyl or substituted alkyl; where Ar is aryl; where X4 and X5 optionally may be linked to form a cyclic structure; where Y1 – Y4 are independently Ar or substituted Ar; where the Y1 – Y4 groups that are bound to the same P atom may also be linked with a carbon to carbon bond, CH2, NH, NR, NAr, or O; and where n is 0 or 1.

    Abstract: A method for forming 1,3,5,7-tetraalkyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaadamantane includes obtaining a solution comprising an ethereal solvent and an aluminum hydride, adding dichloro(2,4-dimethoxyphenyl)phosphine to the solution to produce 2,4-dimethoxyphenylphosphine, and reacting the 2,4-dimethoxyphenylphosphine with an acidic mixture comprising diones to produce 1,3,5,7-tetraalkyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaadamantane. The solution has a temperature from greater than -20 C to 50 C throughout the method. Another method for forming 1,3,5,7-tetraalkyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaadamantane includes obtaining dichloro(2,4-dimethoxyphenyl)phosphine, forming 2,4-dimethoxyphenylphosphine by adding the dichloro(2,4-dimethoxyphenyl)phosphine to a solution comprising at least one solvent and an aluminum hydride, reacting the 2,4-dimethoxyphenylphosphine with a mixture to produce 1,3,5,7-tetraalkyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaadamantane. The mixture includes an acid selected from the group consisting of Lewis acids, sulfonic Bronsted acids, and mixtures thereof, an aromatic or non-aromatic hydrocarbons; and acetylacetone.

    Abstract: Catalyst compositions are prepared by contacting a palladium source and 1,3,5,7-tetramethyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaadamantane and a methoxyocta-diene compound, in a primary aliphatic alcohol, under suitable conditions including a ratio of equivalents of palladium to equivalents of 1,3,5,7-tetramethyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaadamantane ranging from greater than 1:1 to 1:1.3. The result is a complex of palladium, a 1,3,5,7-tetramethyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaada-mantane ligand, and a ligand selected from a methoxyoctadiene ligand, an octadienyl ligand, or a protonated octadienyl. Such complexes may, in solution, exhibit surprising solubility and storage stability and are useful in the telomerization of butadiene, which is a step in the production of 1-octene.
