Amines ADMET polymerization

The molybdenum catalyst 2 has been used extensively for ADMET polymerization. This complex is easier to handle than the tungsten analog and is more tolerant of functionality. This complex has allowed the synthesis of polymers containing esters, carbonates, ethers, sulfides, aromatic amines, boronates, dichlorosilanes, siloxanes, acetals, and conjugated carbon-carbon double bonds [38-45]. Aldehydes, ketones, and protic functionahty are not tolerated. The molybdenum alkylidene will react with aldehydes and ketones, but not esters, in a Wittig fashion [64]. 

More recently, ADMET was used to synthesize precision poly(ethylene-co-vinyl amine) with primary amine branches placed on every 9th, 15th, 19th, or 21st carbon along the PE backbone [81]. This was accomplished by synthesizing a symmetrical diene monomer that included a BOC-protected amine, which was thermally deprotected after polymerization. The thermal deprotection yielded a minimally soluble product, as did chemical approaches to deprotection, but the thermal approach resulted in less sample contamination. This insolubility hampered characterization efforts, but the final deprotected polymer was characterized by solid-state NMR, NMR, and TGA, all of which proved...
