An efficient ruthenium-catalyzedsynthesis of tri-substituted 1,3,5-triazines from alcohols and biguanides under mild conditions has been developed. The reaction occurred in moderate to good yields and tolerated benzyl alcohol containing functionalities such as halogens. Monosubstituted to tetrasubstituted biguanidines also afforded the desired products.
There is provided an electrophoretic particle which contains a core material particle formed of a composition containing a resin, a nitrogen-containing heterocyclic compound having any one of an imino group, a methylol group and an alkoxymethyl group in the molecule and a heterocyclic ring having a nitrogen atom, and a coloring agent.

A base-promoted amination of aromatic halides has been developed using a limited amount of dimethylformamide (DMF) or amine as an amino source. Various arylhalides, including F, Cl, Br, and I, have been successfully aminated in good to excellent yields. Although the amination of aromatic halides with amines or DMF is usually considered as an aromatic nucleophilic substitution (SNAr) process, and the
