Isomer-selective complexation of copper(I) ionic salts towards 1- and 2-allylbenzotriazoles. Synthesis and characterization of CuBF 4·2-all-bta·H2O, CuClO4·2- all-bta, CuClO4·1-all-bta·2-all-bta and CuHSO 4·2-all-bta - The first known example of CuHSO4 π-complexes

The alternating current electrochemical synthesis starting from ethanol solution of Cu(ClO4)2·6H2O, CuSO 4·5H2O and Cu(BF4)2· 6H2O with the equimolar mixture of 1- and 2-allylbenzotriazole (all-bta) has led to a formation of Cu[2-all-bta]ClO4 (I), Cu[2-all-bta]HSO4 (II) and Cu[2-all-bta]BF4·H 2O (III) compounds. The direct interaction between Cu(ClO 4)2·6H2O and the mixture of 1- and 2-allylbenzotriazole in ethanol solution results in an appearance of Cu[(1-all-bta)(2-all-bta)]ClO4 (IV) compound. These results are strikingly different from earlier performed syntheses using the same ligands mixture and copper(II) halides, and producing coordination compounds with 1-allylbenzotriazole only. Compounds I and II are isotypical and crystallize in a monoclinic space group Cc. I: a = 9.5413(10) , b = 12.3171(9) , c = 10.3264(10) , β = 111.155(4)°, V = 1131.78(18) 3, Z = 4. II: a = 9.1707(17) , b = 13.6639(17) , c = 9.4543(17) , β = 105.555(7)°, V = 1141.3(3) 3, Z = 4. The main feature of structures I and II is a chelate-bridging role of the ligand moiety, bonded to one copper ion via CC-bond of the allyl group and nitrogen atom of the triazole core, and to the second Cu+ centre by another N atom. Trigonal-pyramidal copper environment comprises of two nitrogen atoms from different ligand units, CC-bond and oxygen atom at the apical position. The bridging function of both Cu+ cations and 2-all-bta molecules results in the formation of infinite chains. High affinity of BF4- anion to the H2O leads to a formation of compound III including water molecule. It crystallizes in an orthorhombic Pbca space group, a = 13.502(8) b = 11.299(5) c = 16.124(8) , V = 2460(2) 3, Z = 8. The ligand moiety plays the same as in I and II chelate-bridging function, but Cu+, being also bonded to CC group and to two N atoms, is connected with the disordered BF4- anion through the water bridge. In the crystal structure IV the metal ion possesses mixed-isomer surrounding, being bound to N-atom and CC-bond of 2-all-bta molecule, N-atom of 1-all-bta-moiety and O(ClO4 -) atom at apical position. IR spectra confirm rather effective Cu-(CC) bonding.

Green and efficient protocol for N-alkylation of benzotriazole using basic ionic liquid [Bmim]OH as catalyst under solvent-free conditions

N-Alkylation of benzotriazole bearing an acidic hydrogen atom attached to nitrogen with alkyl halides is accomplished in basic ionic liquid [Bmim]OH (1-butyl-3-methylimidazolium hydroxide) under solvent-free conditions. The procedure is convenient and efficient and generally affords the N-alkylated product. Taylor & Francis Group, LLC.

Aqueous micellar medium in organic synthesis: Alkylations and Michael reactions of benzotriazole

The feasibility of aqueous micelles of cetyltrimethylammonium bromide in catalyzing C-N bond formation has been studied with respect to N-alkylations of benzotriazole (Bt). Alkylations with various alkylating agents and the addition of Bt across activated double bonds in the Michael fashion occurred successfully in fair-to-good yields in the aqueous micellar regime. These reactions provided a mixture of N-1 and N-2 alkylated products, with a marked preference for N-1 over N-2 isomers. Micellar catalysis has been evaluated experimentally to indicate over a 50% micellar contribution to these alkylations in contrast to their aqueous counterparts. Since, N-alkyl benzotriazoles are of potential biological interest, the present micellar procedure offers a convenient alternative to other available methods.
