Abstract
The present disclosure provides methods for making quinolinyldiamine products from quinolinyl starting materials. In addition, the quinolinyldiamines can be used as ligands or ligand precursors for catalysts, e.g. for use in olefin polymerization.
Claims36
A method for making a quinolinyldiamine, comprising:
- introducing an acid solution, a nitrite, and phosphorous oxoacid to a compound represented by Formula C or Formula K:
- wherein R8, R9, R10′, R11′, and R14 are independently hydrogen, hydrocarbyl, alkoxy, silyl, amino, aryloxy, substituted hydrocarbyl, halogen, or phosphino, or any two of R8 & R9, R9 & R10′, R10′ & R14, and R10′ & R11′ are joined to form a substituted or unsubstituted hydrocarbyl or heterocyclic ring, wherein the ring has 5, 6, 7, or 8 ring atoms, and wherein the ring is saturated or unsaturated;
- and
- obtaining a compound represented by Formula D or Formula L:
- wherein R8, R9, R10′, R11′, and R14 are independently hydrogen, hydrocarbyl, alkoxy, silyl, amino, aryloxy, substituted hydrocarbyl, halogen, or phosphino, or any two of R8 & R9, R9 & R10′, R10′ & R14, and R10′ & R11′ are joined to form a substituted or unsubstituted hydrocarbyl or heterocyclic ring, wherein the ring has 5, 6, 7, or 8 ring atoms, and wherein the ring is saturated or unsaturated.
