  Cycloaddition of Coordinated Diazoalkanes to Ethene To Yield 3H-Pyrazole Derivatives

  摘要：

  Diazoalkane complexes [Ru(eta(5)-C5H5)(N(2)CAr1Ar2)(PPh3)L]BPh4 (1, 2; Ar1 = Ph, Ar2 = p-tolyl; Ar1Ar2 = C12H8; L = P(OMe)(3), P(OEt)(3)) were prepared by allowing compounds RuCl(eta(5)-C5H5)(PPh3)L to react with diazoalkane in ethanol. Treatment of complexes 1 and 2 with ethylene under mild conditions (1 atm, room temperature) led not only to the ethylene complexes [Ru(eta(5)-C5H5)(eta(2)-CH2=CH2)(PPh3)L]BPh4 (5, 6) but also to dipolar (3 + 2) cycloaddition, affording the 3H-pyrazole derivatives [Ru(eta(5)-C5H5){eta(1)-N=NC(Ar1Ar2)CH2CH2}(PPh3)L]BPh4 (3, 4). The propylene complexes [Ru(eta(5)-C5H5)(eta(2)-CH3CH=CH2)(PPh3)L]BPh4 (7, 8) were also prepared. The compounds were characterized by spectroscopy and by X-ray crystal structure determinations of 2a, 3b, and 7.

The alkyl propiolates HC≡CCOOR1 (R1 = Me, Et) also reacted with complexes 2 to give the 3H-pyrazole complexes [Ru(η5-C5H5)η1-N═NC(Ar1Ar2)C(COOR1)═CH}(PPh3)P(OMe)3}]BPh4 (27, 28). The complexes were characterized by spectroscopy and by X-ray crystal structure determinations of [Ru(η5-C5H5)η1-N═C(CN)CH2C(Ph)(p-tolyl)NH}(PPh3)P(OMe)3}]BPh4 (19b), [R
