supporting information; experimental part, p. 18003 - 18005 (2011/12/16)
Hydrogen sulfide (H2S) has recently been identified as a biological response modifier. Here, we report the design and synthesis of a novel fluorescence probe for H2S, HSip-1, utilizing azamacrocyclic copper(II) ion complex chemistry
An improved synthesis of 1,4,7-triazacyclononanes (tacns) and 1,4,7,10-tetraazacyclododecanes (cyclens)
Huang, Jianying,Zhou, Zhongyuan,Tak, Hang Chan
experimental part, p. 2341 - 2344 (2010/02/28)
Reaction of tosylbis[2-(tosyloxy)ethyl]amine with ethylenediamine gives 1-tosyl-1,4,7-triazacyclononane in good yield. A similar reaction of tosylbis[2-(tosyloxy)ethyl]amine with diethylenetriamine gives 1-tosyl-1,4,7,10-tetraazacyclododecane. These tosyl
Rare-earth metal alkyl and hydride complexes stabilized by a cyclen-derived [NNNN] macrocyclic ancillary ligand
Ohashi, Masato,Konkol, Marcin,Del Rosal, Iker,Poteau, Romuald,Maron, Laurent,Okuda, Jun
, p. 6920 - 6921 (2008/12/20)
A trinuclear rare-earth metal hydride complex was synthesized from the dialkyl complex supported by a monoanionic [NNNN] macrocycle and shown to catalyze the hydrosilylation of olefins efficiently. Copyright
1,4-Bis-(4-toluenesulphonyl)-1,4,7,10-tetraazacyclododecane from the direct tosylation of 1,4,7,10-tetraazacyclododecane
Hill, Jonathan P.,Anson, Christopher E.,Powell, Annie K.
, p. 7301 - 7302 (2007/10/03)
The reaction between 1,4,7,10-tetraazacyclododecane and 4-toluenesulphonyl chloride in triethylamine/chloroform yields both the disubstituted isomers of bis-(4-toluenesulphonyl)-1,4,7,10-tetraazacyclododecane. This has been confirmed by 1H NMR
Concerning two-metal cooperativity in model phosphate hydrolysis
Leivers, Martin,Breslow, Ronald
, p. 345 - 356 (2007/10/03)
Three series of bimetallic ligands were tested for cooperativity in the hydrolysis of phosphate esters. It was shown that rate enhancements were in part contributed by binding to the hydrophobic linkers when the substrates were also hydrophobic, and two metal cooperativity was not found to be present. Kinetic order tests were performed and shown to be superior to previous methods for analyzing cooperativity.
Regioselective synthesis of 1,7-diprotected 1,4,7,10-tetraazacyclododecane and preparation of a dialcohol dicarboxylic macrocyclic ligand
Dumont, Arnaud,Jacques, Vincent,Qixiu, Peng,Desreux, Jean F.
, p. 3707 - 3710 (2007/10/02)
The reaction of 1,4,7,10-tetraazacyclododecane with p-toluenesulfonyl chloride in pyridine or with diethyl phosphite and CCl4 in a water/CH2Cl2 mixture yields selectively the 1,7-diprotected regioisomer.The 1,7-diprotected tetraaza cycles are interesting
