A novel donor-acceptor bisphthalocyanine (bis-Pc, 1) in which two different Pc units (Zn(II)-Pc and Ni(II)-Pc) are linked via vinylene spacers to the pseudopara positions of a central [2.2]paracyclophane moiety is described. The synthesis of 1 is achieved by two successive Heck reactions of pseudopara-divinyl[2.2]paracyclophane 9 with, sequentially, a zinc(II)- and a nickel(II)-iodophthalocyani...

A series of single-walled carbon nanotube precursors, C3h-symmetric cyclotri(ethynylene)(biphenyl-2,4'-diyl) and cyclotri(ethynylene)(p-terphenyl-2,4″-diyl), have been prepared by a linear stepwise oligomerization-cyclization route and by statistical intermolecular cyclooligomerization. In addition to producing these members of a novel class of arylene ethynylene macrocycles, 1 and 2, the latte...

The crystal structure of the proton-transfer compound of 1,1'-biphenyl-4,4'-diamine (benzidine) with 3,5-dinitrosalicylic acid, viz. 1,1'-biphenyl-4,4'-diaminium bis(4'-amino-1,1'-biphenyl-4-aminium) tetrakis(2-carboxy-4,6-dinitrophenolate) ethanol disolvate, C(12)H(14)N(2)(2+)x2C(12)H(13)N(2)(+)x4C(7)H(3)N(2)O(7)(-)x2C(2)H(6)O, shows the presence of both diprotonated and monoprotonated benzidi...

Sharma Dept. of Pharmaceutical Sciences, Dr.Hari Singh Gour University Sagar (M.P) 470003 India Department of Chemistry Yadhunath Mahavidyalya Bhind (M.P) 477001 India Email: [email protected] Abstract A new series of non peptide angiotensin (A-II) receptor antagonist has been prepared. This N-(biphenyl methyl) imidazoles e.g. Some new 4'-{5-amino2-[2-substituted-phenylamino)-ph...

MCM-41@L-Arg@Pd(0) has been prepared by some consequence reactions. This nano structural material has been characterized via different technique including: XRD, TGA, BET, EDS, X-Ray maps, SEM, ICP-OES and FT-IR analysis. The synthesis of a variety of biphenyl compounds has been achieved successfully via a reaction of aryl halides with arylboronic acids in the presence of this nanostructure (MCM...

A series of methyl 6-Chloro-2-Substitued-1-[2-(1H-tetrazol-5-yl)-biphenyl-4-ylmethyl]1H-benzoimidazol-5-ylamine were successfully synthesized. Benzimidazoles were prepared by condensation of 4-chloro-o-phenylenediamine with substituted aryl, aldehyde condensation with biphenyl tetrazole group and reduction stannous chloride dihydrate. An insertion-cyclization strategy was involved during synthe...

The crystal structure of the polymeric title complex, [Zn(C(14)H(8)O(4))](n), is composed of layers parallel to (110) formed by linking of Zn-carboxyl-ate chains with biphenyl units of the biphenyl-2,4'-dicarboxyl-ate (bpdc) ligands. The Zn(II) atom is five-coordinated in a distorted square-pyramidal geometry by five O atoms from four bpdc ligands. The dihedral angle between the benzene rings i...
