Electrospun nanofibers with antibacterial activity are greatly promising for medical treatment and water purification. Herein we report antibacterial nanofibers electrospun from a series of poly(dimethylamino ethyl methacrylate-co-alkyl methacrylates) (poly(DMAEMA-co-AMA)) and to distinguish the effects of free and cross-linked cations derived

The discovery of a novel arylpalladium(II) reduction enables the synthesis of diarylmethanes via reductive benzylation. Benzyl chlorides were found to be the major source of hydride, acting as an alkylating agent and an aprotic surrogate for benzyl alcohol. This represents

Efficient Csp(3)-Csp(3) Suzuki couplings have been developed with both potassium cyclopropyl- and alkoxymethyltrifluoroborates. Moderate to good yields have been achieved in the cross-coupling of potassium cyclopropyltrifluoroborate with benzyl chlorides possessing electron-donating or electron-withdrawing substituents. Benzyl chloride was also successfully cross-coupled

Cute CO! An interesting and straightforward procedure for the carbonylative synthesis of chromenones from readily available salicylic aldehydes and benzyl chlorides has been developed (see scheme; DPPP = 1,3-bis(diphenylphosphino)propane).

A novel Ni-catalyzed carboxylation of benzyl halides with CO(2) has been developed. The described carboxylation reaction proceeds under mild conditions (atmospheric CO(2) pressure) at room temperature. Unlike other routes for similar means, our method does not require well-defined and sensitive

α-diimine iron complexes have been suggested to catalyse polymerisation via two distinct pathways, depending on the spin state of the iron complex. Here, we study a typical complex of this family, (R'')[N,N]FeCl(2), with [N,N] = Cy-N=CR''-CR''=N-Cy (Cy = cyclohexyl, R''

The reaction mechanism of the Pd-catalyzed benzyl/allyl coupling of benzyl chloride with allyltributylstannan, resulting in the dearomatization of the benzyl group, was studied using density functional theory calculations at the B3LYP level. The calculations indicate that the intermediate (eta(3)-benzyl)(eta(1)-allyl)Pd(PH(3)) is

The 2-aryl-2,3,5,6,7,8-hexahydro[1]benzothieno[2,3-d]pyrimidin-4(1H)-ones and 2-aryl-5,6,7,8-tetrahydro[1]benzothieno[2,3-d]pyrimidin-4(3H)-ones have been diversified by alkylation reactions, applying benzylchlorides and N-substituted 2-chloroacetamides as alkylating agents. Under the found uniform conditions the substitution direction does not depend on the structure of the alkylating agent and gives monoalkylated products
