Selective cation and anion guest binding in host selenazamacrocycles

Autor: Upali Patel, Colin D. McMillen, Mohammed A. Abbas, Julia L. Brumaghim

Publikováno v: Dalton Transactions. 47:12066-12070

We report selenazamacrocycle hosts that are the first system to change guest binding affinity from cation to anion depending upon macrocycle oxidation/reduction. Selective cation (Fe2+) or anion (BF4-) binding occurs with both ions present and under

Publikováno v: Organometallics. 29:4265-4275

22-Membered mercuraazametallamacrocycles 6, 7, and 12 have been synthesized by dipodal condensation (2 + 2) of bis(o-formylphenyl)mercury (11) and 1,2-disubstituted amines. Reduction of macrocycle 6 with sodium borohydride afforded novel 11-membered

Synthesis and Characterization of Some New 22‐Membered Chalcogenoaza Macrocycles and Their Co II and Ni II Complexes

Autor: Harkesh B. Singh, Upali Patel, Ray J. Butcher

Publikováno v: European Journal of Inorganic Chemistry. 2006:5089-5097

The [2+2] cyclocondensation of bis(o-formylphenyl)chalcogenides (9, 10) with trans-1,2-diaminocyclohexane affords novel macrocyclic ligands 11 and 12 in very good yields. Crystals of 11 are triclinic, space group P with a = 11.4037(11), b = 11.8184(1

Bi- and terpyridyl platinum(II) chloro complexes: molecular catalysts for the photogeneration of hydrogen from water or simply precursors for colloidal platinum?

Autor: Wei Zhao, Felix N. Castellano, Pingwu Du, Jacob Schneider, Richard M. Eisenberg, Fan Li, Upali Patel

Publikováno v: Journal of the American Chemical Society. 130(15)

Platinum(II) bi- and terpyridyl chloro complexes, Pt(dcbpy)Cl2 and [Pt(ttpy)Cl]+, where dcbpy = 4,4'-dicarboxyl-2,2'-bipyridine and ttpy = 4-tolyl-2,2':6',2''-terpyridine, are used to investigate the nature of the active catalyst for the photocatalyt
