Conclusions

  1. 1.

    We were the first to study the dehydrogenation of 1,4-dihydropyridines using catalytic amounts of homogeneous Pd catalysts and it was shown that 2,6-dimethyl-3,5-dicarbethoxy-1,4-dihydropyridine and its 4-substituted alkyl-(CH3-C4H9) and aryl- (C6H5, o-C6H4OH, CH=CH-C6H5, p-C6H4-OCH3) derivatives are easily converted to the corresponding pyridines under the influence (10 h, 100°) of the catalyst: Pd(acac)2-P(C4H9)3-Al(C2H5)3-CF3CO2H (1∶3∶3∶10).

  2. 2)

    When substituted 1,4-dihydropyridines are dehydrogenated in the presence of 1,5-cyclooctadienes the latter undergo simultaneous selective hydrogenation to the corresponding cyclooctenes.
