Synthesis of Thiadiazole Hemihexaporphyrazine Bearing iso-Propyloxy Groups and its Trinuclear NiII Complex

Abstract

A thiadiazole derived expanded "hemihexaporphyrazine" of ABABAB-type has been prepared via cyclomerization reaction of 2,5-diamino-1,3,4-thiadiazole and 3,6-diisopropyl

Synthesis and Properties of Hexa(4-tert-butylphenoxy) Substituted [30]Trithiadodecaazahexaphyrin and its Metal Complexes

“…[9,10] With the goal of detailed characterization and revealing potential applications of this young class of compounds, substituted and unsubstituted thiadiazoloporphyrinoids have been obtained very recently. [3,7,11,12] It has been found that unsubstituted thiadiazoloporphyrinoids are insoluble in most of organic solvents. An introduction of bulky substituents on the periphery of their molecules led to a significant increase of their solubility that allowed a purification and characterization.…”

Homotrinuclear Сomplexes of [30]Trithiadodecaazahexaphyrine with Transition Metals: Ni(II), Cu(II) and Mn(II)

“…[7][8][9] Among expanded compounds, Mc's of ABABAB-type (hemihexaphyrazine, H 3 Hhp) containing six consecutively interlinked 1,3,4-thiadiazole (A) and isoindole (B) subunits bridged by nitrogen atoms [10,11] induce a particular interest. Indeed, various substituted macroheterocyclic compounds of this type were synthesized to date [12][13][14][15][16][17][18] and their structures were confirmed by gas electron diffraction (GED) [19,20] and single crystal X-ray diffraction [21] methods. It was established that compounds of this type have a nonaromatic macrocyclic backbone containing 30 carbon and nitrogen atoms which form an expanded coordination cavity compared to that of porphyrins and phthalocyanines.…”
