This invention relates to a composition, comprising: an unsaturated functionalized monomer of from about 5 to about 30 carbon atoms, which is: (a) polymerized to form a functionalized polymer; (b) copolymerized with a comonomer to form a functionalized copolymer; or (c) reacted with an enophilic reagent to form a polyfunctionalized monomer. The polyfunctionalized monomer may be polymerized to form a polyfunctionalized polymer which may be further reacted with one or more additional reagents. The invention relates to lubricants, functional fluids, fuels, dispersants, detergents and polymeric resins.

valuable primary and secondary amines is reported using a sequential procedure of hydroaminomethylation and Pd-catalyzed hydrogenolysis. The hydroaminomethylation reaction was catalyzed by a cationic Rh(I) iminopyridyl complex and the N-alkylated benzylamines were produced with high chemoselectivity, albeit as mixtures of linear and branched products. Performing the hydrogenolysis reaction using 10% Pd/C
