“…[27] In view of recent results from Suzuki et al, [10][11][12][13][14][15] we anticipated that the intermediacy of arynes containing single anellated cyclobutane rings should be possible. 1,4-Dibromo-2,5-dimethoxybenzene (6) was viewed as a favorable starting material, because no bent systems such as 5 need be expected.…”

“…[9] Benzene rings containing more than one anellated cyclobutane ring are much less common, although Suzuki recently reported some significant progress in this field. [10][11][12][13][14][15] Remarkably, the complexes 1 [16] and 2 [17] are the only examples of arene tricarbonylchromium complexes containing more than one anellated cyclobutane ring. They do not bear functional groups, and their chemistry has not been investigated.…”

“…[11][12][13][14][15][16] Of these, elimination from aryl triflates [15] is currently most frequently used. [7][8][9][10][17][18][19][20][21][22][23][24][25][26] The field has recently been reviewed by Lloyd-Jones. [27] In the context of our interest in (arene)tricarbonylchromium complexes we attempted to generate (aryne)tricarbonylchromium complexes 1 as reactive intermediates.…”

“…[1,2] In Substanz konnte C 2 O 3 jedoch bisher nicht isoliert werden, und einer thermodynamischen Analyse von Perk und Liebman zufolge ist Oxirandion ca. 230 kJ mol À1 instabiler als die getrennten Fragmente CO + CO 2 .…”

“…[1,2] In Substanz konnte C 2 O 3 jedoch bisher nicht isoliert werden, und einer thermodynamischen Analyse von Perk und Liebman zufolge ist Oxirandion ca. 230 kJ mol À1 instabiler als die getrennten Fragmente CO + CO 2 . [3] Dieser Wert stimmt mit einer berechnteten Exothermie von 222 kJ mol À1 für den Zerfall von cyclischem C 2 O 3 in CO + CO 2 gut überein, die Peppe et al [4] bei Versuchen zur Erzeugung von neutralem C 2 O 3 aus geeigneten ionischen Vorstufen mithilfe der Neutralisations-Reionisations-Massenspektrometrie [5] ermittelten.…”
