Novel 36-membered dodecanuclear manganese metalladiazamacrocycle: Novel 36-membered dodecanuclear manganese metalladiazamacrocycle. John, Rohith P.; Lee, Kyungjae; Lah, Myoung Soo (Department of Chemistry and Applied Chemistry, Hanyang University, AnsanKyunggi-do 426-791, S. Korea). Chemical Communications (Cambridge, United Kingdom), (23), 2660-2661 (English) 2004 Royal Society of Chemistry. CODEN: CHCOFS.Several reagents with their cas registry numbers 828266-03-1 and 13991-37-2 are used here. ISSN: 1359-7345. DOCUMENT TYPE: Journal CA Section: 78 (Inorganic Chemicals and Reactions) Section cross-reference(s): 75 A novel dodecanuclear Mn metalladiazamacrocycle was synthesized employing a new pentadentate ligand N-2-pentenoylsalicylhydrazide (H3tpeshz) by supramol. self-assembly. The backbone of this metal-org. assembly is a repeating unit of an M-N-N-M linkage that extends to complete a 36-membered cyclic structure involving 12 Mn(III) centers. Successive Mn centers are in a chem. different ×××ABABAB×××-type environment while the chirality varies as ×××LLDDLL×××. The unique arrangement of Mn centers results in a highly puckered metalladiazamacrocycle with an S6-point group symmetry. .

U.S. US 4439226 A 27 Mar 1984, 7 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: A01N043-52; C07D235-08. NCL: 071092000. APPLICATION: US 82-419865 20 Sep 1982. DOCUMENT TYPE: Patent CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Section cross-reference(s): 5 Acids and esters I (n = 1 and R = CF3; R1 = H, Me, Et; R2 = Me, Et, CH2OMe; m = 0, 1, 2; R3 = H, alkyl), which were prepd., exhibited herbicidal activity. 13991-37-2 which is the cas registry number is also used here. Diphenylamine deriv. II was contacted with H over Pd, and the diamine obtained was heated with HC(OEt)3 to give I (Rn = 5-CF3, R1 = H, R2 = Me, m = 0, R3 = Et). .
