  It is shown that azulenes react with dimethyl acetylenedicarboxylate (ADM) in solvents such as toluene, dioxan, or MeCN in the presence of 2 mol-% [RuH2(PPh3)4] already at temperatures as low as 100° and lead to the formation of the corresponding heptalene-1,2-dicarboxylates in excellent yields (Tables 1 and 2). The Ru-catalyzed reaction of ADM with 1-(tert-butyl)-4,6,8-trimethylazulene (31) takes

  结果表明，在2 mol％[RuH 2（PPh 3）4 ]的存在下，天青石已经在溶剂（如甲苯，二恶烷或MeCN中）与乙二甲基二羧酸二甲酯（ADM）反应，而该温度已低至100°C，并导致形成相应的庚烯1,2-二羧酸庚酯的产率很高（表1和2）。ADM与1-（的钌催化反应叔丁基）-4,6,8-trimethylazulene（31）发生即使在室温下，得到初级三环加成产物32和其热复古-狄尔斯-阿尔德产物4,6,8-三甲基az-1,2-二羧酸二甲酯（21；方案4）。在MeCN中100°时，32的产率为90％的21，而只有10％的相应的庚烯。这些观察结果表明，[RuH 2（PPh 3）4 ]催化了从天青石和ADM热形成庚烷的第一步，该第一步发生在非极性溶剂（例如，四氢化萘或十氢化萘中），温度> 180°（参见方案1）。

The new complexes 3 catalyze the formation of heptalene-1,2-dicarboxylates 2 from dimethyl acetylenedicarboxylate (ADM) and the corresponding azulenes 1 just as effectively as [RuH2(PPh3)4] and the analogous [RhH(PPh3)4] complex in MeCN solution (Table 3).

  A number of azulenes; 1, in particular those with pi-substituents at C(6) such as phenyl, 3,5-dimethylphenyl, and 4-biphenyl, have been reacted with 3 mol-equiv. of dimethyl acetylenedicarboxylate (ADM) in MeCN at 110degrees (cf. Scheme 1). Main products had been, in all cases, the corresponding heptalene-4,5-dicarboxylates 2. However, a whole number of side products, mainly rearranged (1 + 2)-adducts with two molecules of ADM, in amounts of 0.2-9% were also isolated and characterized (cf. Scheme 2). The 2a,8a-dihydro-3,4-ethenoazulene-1,2-dicarboxylates 14, formed by energetically favorable ring closure from the solvent-stabilized zwitterions 15, resulting from bond heterolysis in the primary cycloadducts 12 (cf. Scheme 3), have been mechanistically identified as the pivotal intermediates responsible for the formation of all side product (cf. Schemes 5, 9, 12, and 13). Deuterium-labeling experiments were in agreement with the proposed mechanisms, indicating that si,gmatropic [1,5s]-H shifts in 14 (cf. Scheme 6) as well as isoconjugate [1,4s]-H shifts in resonance-stabilized zwitterions of type 21 (cf. Scheme 9) are the crucial steps for side-product formation. It is postulated that a concluding antarafacial 8e-dyotropic rearrangement is responsible for the appearance of the 2,4a-dihydrophenanthrene-tetracarboxylates of type trans-6 (cf. Scheme 9) in the reaction mixtures, which further rearrange thermally by a not fully understood mechanism into the isomeric tetracarboxylates 7 (cf. Schemes 10 and 11). Most surprising is the presence of a small amount (0.3-1%) of the azulene-4,5,7,8-tetracarboxylate 9 in the reaction mixture of azulene 1a and ADM. It is proposed that the formation of 9 is the result of a [1,5s]-C shift in the spiro-linked intermediates 24, which, after prototropic shift and take-up of a third molecule of ADM, disintegrate by a retro-Diels-Alder reaction into 9 and the phthalic diesters 30 (cf. Scheme 12). The UV/VIS spectra of the pi-substituted heptalene-4,5-dicarboxylates 2d-2f and their double-bond shifted (DBS) forms 2d-2f (cf Table 4 and Figs. 9-12) exhibit in comparison with the heptatene-dicarboxylates 2a and 2'a, carrying a t-Bu group at C(8), only marginal differences, which are mainly found in the relative intensity and position of heptatene bands II and III.

  The reaction of guaiazulene (4) and dimethyl acetylenedicarboxylate (ADM) in tetralin or toluene, catalyzed by 5 mol-% of trifluoroacetic acid (TFA) at ambient temperature, leads to the formation of the corresponding heptalene-4,5-dicarboxylate 6 and a guaiazulenyl-substituted 2,2a,4a,8b-tetrahydrocyclopent[cd]azulene derivative 7 beside the expected guaiazulenyl-substituted ethenedicarboxylates (E)-5 and (2)-5 as main products (Scheme 2). The structure of 7 was unequivocally established by an X-ray crystal-structure analysis ( Fig. I). Precursor of 7 must be the 2a,4a-dihydrocyclopent[cd]azulene-3,4-dicarboxylate 9 which reacts, under TFA catalysis, with a second molecule of 4 (Scheme 3). No formation of products of type 7 has been observed in the TFA-catalyzed reaction of 4,6,8-trimethyl- and 1,4,6,8-tetramethylazulene (13 and 16, respectively) and ADM (Scheme 4). On the other hand, the TFA-catalyzed reaction of azulene (18) itself and ADM at ambient temperature gives rise to a whole variety of new products (Scheme 5), the major part of which is derived from dimethyl 2a,4a-dihydrocyclopent[cd]azulene 3,4-dicarboxylate (25) as the main intermediate (Scheme 6). Nevertheless, for the formation of the 2a,4a,6,8b-tetrahydrocyclobut[a]azulene derivatives (E)-24a and (E)-24b, a corresponding 2a,8b-dihydro precursor 29 has to be postulated as crucial intermediate (Scheme 8).
