A one-pot, three-component, Cu(I)-catalyzed coupling of primary hydrazines, 5-chloropentan-2-one, and terminalalkynes was developed. The resulting 1-aza-6,7-dehydrotropanes compose a new class of substances while related 1-azatropanes are scarcely described in literature and closely resemble tropane alkaloids. Hydrogenation of the double bond in 1-aza-6,7-dehydrotropanes triggered a rearrangement

The reaction of 1,1-dimethyl-1-phenacylhydrazinium bromide with 1 M aqueous sodiumhydroxide give benzoic acid, 3-phenyl-1-methylpyrazole, 5-benzoyl-3-phenyl-1-methylpyrazole, and benzonitrile as the major components; the expected product, 2-benzoyl-5-phenylimidazole was formed in only small amounts. Mechanisms to rationalize the formation of the major products are discussed.

The present invention provides a method, an apparatus and chemical products for treating petroleum equipment wherein a fluid is flowing, preferably of the hydrocarbon type, and wherein treating is performed by establishing a closed or semi-closed flow circulation loop, during the normal production operations of the equipment. The treatment can refer to the cleaning of equipment, to yield improvement as compared to normal run conditions and/or to a reduction of coke formation and/or to coke removal on catalysts.
