Expanded Phthalocyanine Analogues: Synthesis and Characterization of New Triazole-Derived Annulenes Containing Six Heterocyclic Subunits

Synthesechemie expandierter Porphyrine

“…Die ersten expandierten Phthalocyanine wurden kürzlich von Torres et al beschrieben 103. Längeres Erhitzen der aus drei Untereinheiten bestehenden acyclischen Zwischenstufen 93 a – f in Ethoxyethanol führte unter Selbstkondensation zu den metallierten Heteroannulenen 94 a – f (Schema ).…”

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

“…2, 3,14,15,26,36:12,17:24,10:19,22:31,p,2,4,9,11,12,14,19,21,22,24,4,6,8,10,12,14,16,18,20,22,24,26,28,4. 3,6-Diisopropyloxyphthalonitrile (6, 244 mg, 1.0 mmol) and 2,5-diamino-1,3,4-thiadiazole, (7, 116 mg, 1.0 mmol) were dissolved in dry isopropanol (8 ml) at reflux.…”

“…In the last decades, chemistry of azaporphyrins has been widely advanced due to the persistent work on this field. [12][13][14] Herein, the one problem for the rational design of expanded azaporphyrins, i.e. the spontaneous formation of macrocycles of the favorable structures and open-chain intermediates, has been overcome by the working out of some synthetic approaches.…”

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

“…[1][2][3][4][5][6] A principal aspect derived from structures of these compounds is aromaticity of central core and applicability of Hückel's rule to describe its electronic structure. [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.…”
