Using a number of cyclic alpha,beta-unsaturated oximes of the terpene series and sonic Simplest model compounds as examples, unsaturated oximes bearing a hydrogen atom it the beta-carbon atom were demonstrated to be converted into beta-hydroxyiminonitroalkenes under the action of sodium nitrite and acetic acid in methanol. In the case of the introduction of an alkyl substituent at the terminal carbon atom of the diene C=C-C=NOH fragment, the reaction performed under the same conditions gave rise exclusively to conjugated ketone (a deoximation product).

Reaction of (μ-H)2Os3(CO)10 cluster with (1S,3S,6R)-3-dimethylaminocarane-4-one E-oxime results in loss of dimethylamino group and formation of (μ-H)Os3(CO)10(μ-ONC) cluster (43%). Treatment of cluster Os3(CO)11(NCCH3) with (1S,3S,6R)-3-mercaptocaran-4-one E-oxime gives cluster (μ-H)Os3(CO)10(μ-S⋯) in 86%, whose structure was proved by X-ray single crystal analysis. Decarbonylation of the later
(μ-H)2 Os 3(CO)10团簇与(1 S,3 S,6 R)-3-二甲基氨基戊烷-4-one E-肟的反应导致二甲基氨基基团的丢失和(μ-H Os 3(CO)10(μ-ONC)簇(43%)。簇的治疗锇3(CO)11(NCCH 3)与(1小号,3小号,6 - [R)-3- mercaptocaran -4-酮ë肟给出簇(μ-H)O的3(CO)10(μ-S⋯)为86%,其结构通过X射线单晶分析证明。与后来的化合物脱羰(CH 3)3 NO导致(μ-H)O的非对映体混合物3(CO)9(μ,η 2 - (小号,Ñ)⋯)以64%的产率簇。

The reaction of nitroso chlorides of natural monoterpene hydrocarbons, 3-carene and alpha-pinene, with simple alpha,omega-diamines (1,2-diaminoethane, 1,3-diaminopropane, piperazine, 1,6-diaminohexane, diethylenetriamine) results in the formation of alpha-amino oximes and bis-alpha-amino oximes. The product structures were proved by spectroscopy. The procedures of separation and purification of diamino oximes and diamino dioximes are described. Detailed analysis of the H-1 and C-13 NMR spectra of the new chiral nitrogen-containing derivatives was carried out.
