Photoactivated Healable Vitrimeric Copolymers

A composite polymer based on vinylogous urethane vitrimer bonding with both photodimerizable and thermally exchangeable functionalities is described. Polymers containing various ratios of photodimerizable diaminoanthracene monomers and thermally exchangeable diaminoalkyl monomers linked by a common bisacetoacetate group are studied. It is demonstrated that alkyl amines undergo the necessary thermal exchange reactions for vinylogous urethane vitrimers, while aromatic amines do not. UV-induced dimerization of the anthracene units results in changes to the rheological properties and the glass transition temperature due to polymer cross-linking. Rapid and near-complete scratch healing upon heating is demonstrated, with a tunable onset temperature for healing controlled by UV irradiation. The viability of a composite vitrimeric system, wherein vitrimeric monomers are combined with non-vitrimeric, stimuli-responsive monomers to generate random copolymers with new properties, is demonstrated.

Manganese (III) acetate mediated synthesis of polysubstituted pyrroles under solvent-free ball milling

Under solvent-free ball milling conditions, a simple and mild method was developed for efficient synthesis of 2,5-dimethyl-3,4-dicarboxylate-pyrroles and N-substituted 3,4-diphenylpyrroles via condensation-annulation of amines with acetoacetate and 2-phen

AlCl3-promoted cyclization of β-keto derivatives with in situ generated enamines under solvent-free high speed ball milling: An efficient one-pot access to polysubstituted 1,4-dihydropyridines

Under high speed ball milling (HSBM), a simple method for efficient synthesis of structurally diverse polysubstituted 1,4-dihydropyridines is developed via AlCl3-promoted Robinson-like cyclization of β-keto derivatives with in situ generated enamines. This one-pot protocol exhibits the advantages of high chemoselectivity, short reaction time, good functional group tolerance, mild reaction condition and easy work-up.
