摘要:
Contacting a LIO with a borane isomerization catalyst in a reaction vessel to form a mixture that includes an adduct formed from the LIO and the borane isomerization catalyst, the adduct having an alkyl group bonded to boron at a non-terminal position of the alkyl group, isomerizing the adduct to move the alkyl group bonded to boron to a terminal position of the alkyl group, and dehydroborating the adduct in the presence of a scavenger olefin to form a LAO and a scavenger adduct that is formed from the scavenger olefin and the borane isomerization catalyst.

摘要:
This invention concerns modified fluorosulfonic acid compounds possessing a sulfonic acid fluoride, chloride or ester group or a sulfonic acid or a salt of a sulfonic acid group at one end and respectively a hydrolyzable or hydrolyzed silane group at the other end, said sulfonic group being adjacent a substantially fluorinated bidentate hydrocarbylene group which is in turn adjacent to a hydrocarbylene group linked to said hydrolyzable or hydrolyzed silane group. Self-condensation of the latter compounds provides novel siloxanes and polysiloxanes. This invention further concerns novel composites comprising a metal oxide network having incorporated therein a group having the formula: -O)qSi(OH)n-qR mR RfSO3Q, and compositions comprising a solid material having a reactive surface to which surface is attached at least one group having the formula: -O)qSi(OH)n-qR mR RfSO3Q.

摘要:
A method of isomerizing a substance includes combining a substance including a terminal alkenyl group and a substance including a fluorosulfonic acid group in a reaction mixture, and forming a substance including a 2-alkenyl group from the substance including a terminal alkenyl group in the reaction mixture. The method may be used to functionalize a substance, as the substance including a 2-alkenyl group can be reacted with a functionalizing agent to form a substance including a first functional group. The methods may be used to form a dicarboxylic acid, such as suberic acid, from a renewable feedstock.
