Abstract
Disclosed herein is the selective functionalization of one or more hydrocarbons ranging from the longest macromolecules to methane as the smallest. Functionalization is achieved through C—H activation of the one or more hydrocarbons and is carried out by the catalytic complex described herein. Also disclosed is the compound of formula (I) and the compound of formula (II).
Claims27
A method of functionalizing a hydrocarbon comprising:
- providing a compound of formula (I):
- Al(R1)3 (I);
- providing a compound of formula (II):
- Met(R2)n@support (II);
- providing one or more hydrocarbons;
- wherein
- R1 is independently selected at each occurrence thereof from the group consisting of C6-C10 aryl and C1-C10 alkyl;
- Met is selected from the group consisting of zirconium, titanium, hafnium, scandium, yttrium, lanthanum, and lutetium;
- R2 is C1-C4 alkoxy;
- n is 1, 2, 3, or 4;
- and
- support is alumina or sil ica/alumina;
- contacting the compound of f ormula (I) with the compound of formula (II) to form a complex;
- contacting the complex with one or more hydrocarbons in a reaction mixture under reaction conditions effective to functionalize the one or more hydrocarbons, wherein R1 is a group that does not produce a hydride under the reaction conditions;
- and recovering the functionalized one or more hydrocarbons.
A system comprising:
- a compound of formula (I):
- Al(R1)3 (I);
- and
- a compound of formula (II):
- Met(R2)n@support (II),
- wherein
- R1 is independently selected at each occurrence thereof from the group consisting of C6-C10 aryl and C1-C10 alkyl;
- Met is selected from zirconium, titanium, hafnium, scandium, yttrium, lanthanum and lutetium;
- R2 is C1-C4 alkoxy;
- n is 1, 2, 3, or 4;
- and
- support is alumina or silica/alumina;
- wherein the compound of formula (I) and the compound of formula (II) are capable of forming a complex which, when contacted with one or more hydrocarbons under reaction conditions, is effective to functionalize the one or more hydrocarbons, with the proviso that R1 is a group that does not produce a hydride under the reaction conditions.
