• Phase-Transfer Catalyzed Addition of Hydrogen Cyanide to<i>N</i>-Substituted Hydrazones
  作者：Toshiro Chiba、Mitsuhiro Okimoto

  DOI：10.1055/s-1990-26831

  日期：——

  In a two-phase system consisting of aqueous sodium cyanide and an inert organic solvent and containing a phase-transfer catalyst, ketone benzoylhydrazones, tosylhydrazones, and methoxycarbonylhydrazones upon addition of acetic acid readily add hydrogen cyanide to give 2-substituted 1-(1-cyanoalkyl)hydrazines.

  在由水合氰化钠和惰性有机溶剂组成的二相体系中，并含有相转移催化剂的情况下，酮基苯甲酰肼、甲苯磺酰肼以及甲氧羰基肼在加入醋酸后，能容易地加成氢氰酸，生成2-取代的1-(氰基烷基)肼。
• Electrooxidative cyclization of N-acylhydrazones of aldehydes and ketones to .DELTA.3-1,3,4-oxadiazolines and 1,3,4-oxadiazoles

  The electrolytic oxidation of ketone N-acylhydrazones (1) in methanolic sodium acetate induced their intramolecular cyclization to the corresponding 2-methoxy-DELTA(3)-1,3,4-oxadiazolines 3. The thermal stability of a given oxadiazoline and what products were formed by its thermal decomposition was found to depend on the natures of the substituents at C-2. Thus, 2-methoxy-2-phenyloxadiazolines preferentially yielded oxiranes 5, whereas 2-alkyl-2-methoxyoxadiazolines preferentially gave enol ethers 6. 2,2-Dimethoxyoxadiazolines decomposed to the parent ketones and many unidentified products. The electrolytic oxidation of aldehyde N-acylhydrazones 2 gave 2,5-disubstituted 1,3,4-oxadiazoles 4. The oxidative cyclization of the N-benzoylhydrazones of aliphatic aldehydes gave especially high yields of the corresponding heterocycles.

  The photochemistry of 2-methoxy-2-methyl-5,5-dipropyl-Delta(3)-1,3,4-oxadiazoline (1a) and 2,2-dimethoxy-5,5-dipropyl-Delta(3)-1,3,4-oxadiazoline (1b) was investigated. Photolysis (300 nm) of these compounds in solution leads to fragmentation to 4-diazoheptane (major), which slowly forms the corresponding azine. Fragmentation to form 4-heptanone is also observed. Yields of 4-diazoheptane in CH2Cl2 are much larger than those in pentane. 4-Diazoheptane can be trapped with 1-pentene to form a pyrazoline or with methanol to form 4-methoxyheptane. The pyrazoline can be decomposed photochemically to form 1,1,2-tripropylcyclopropane. In solution, 4-diazoheptane is inefficiently photolyzed to dipropylcarbene (DPC), which can be trapped with piperidine or with pyridine in laser flash photolysis experiments. Analysis of the piperidine and pyridine data indicates that the lifetime of DPC in cyclohexane, methylene chloride, or Freon-113 (CF2ClCFCl2) solution at ambient temperature is controlled by 1,2 hydrogen migration to form Z- and E-3-heptene. The lifetime deduced under these conditions is approximate to 300 ps, which is about 20-fold shorter than that of dimethylcarbene in perfluorohexane at ambient temperature. Upon photolysis (254 nm) of oxadiazoline 1a in argon, 4-diazoheptane and 1-methoxydiazoethane are formed. These diazo compounds undergo subsequent photolysis that revealed the formation of methoxy(methyl)carbene and E- and Z-3-heptene. It was not possible to detect DPC in argon at 14 K.
