Fast photochromic sterically hindered benzo[1,3]oxazines

A series of new substituted benzo[1,3]oxazines presenting bulky substituents on the chiral oxazine centre were prepared from isopropyl ketones or substituted cyclohexanones. Laser irradiation of these uncoloured compounds in solution promotes the cleavage

Electrochemical formation of methoxy- and cyano(phenylazo)alkanes from aldehyde and ketone phenylhydrazones

Several aldehyde and ketone phenylhydrazones were electrooxidized in MeOH. Electrooxidation in the presence of KI or tetraethylammonium p-toluenesulfonate as the supporting electrolyte afforded the corresponding methoxy(phenylazo)alkanes, whereas electrooxidation in the presence of KI, NaCN, and HOAc afforded the cyano(phenylazo)alkanes.

Alkylation of Cycloalkanoindoles via Indolylmagnesium Salts: Synthesis of 3H-Indoles and Oxidative Rearrangement to Spiro-3'-ones

Alkylation of cycloalkanoindolylmagnesium iodide with alkyl halides has been analyzed to prepare cycloalkano-3H-indoles, methyl and N,N-dimethylpropyl derivatives.Spiro derivatives appear as secondary products in this reaction.Selectivity and optimization of the reaction has been determined and a mechanism for the formation of the spiro derivative is proposed.

Rearrangement of 3,3-Disubstituted 1-Aryl-4,5-dihydro-5-oxo-3H-1,2,4-triazolium Tetrafluoroborates; Part 2. A Convenient Synthesis of 1,5-Annulated 1,2-Dihydro-2-phenyl-3H-1,2,4-triazol-3-ones

1-Isocyanato-1-(phenylazo)cycloalkanes 3 react with tetrafluoroboric acid to yield 3-spiro substituted 4,5-dihydro-5-oxo-1-phenyl-3H-1,2,4-triazolium tetrafluoroborates 4.Compounds 4 rearrange with ring expansion in good yield to give, after basic workup,

NOVEL CARBON-CARBON BOND CLEAVAGE REACTIONS OF α-AZOHYDROPEROXIDES

1-Phenylazo-1-hydroperoxycyclohexanes, easily prepared by the autoxidation of cyclohexanone phenyl hydrazones, have been found to undergo C(1)-C(2) bond cleavages when treated with acids, bases, or reducing reagents under mild conditions.Thus 6-oxoalkanoic acids and their derivatives have been obtained in good yields from 2-hydroxycyclohexanone derivatives.The 2-hydroxyl group seems to play an important role for the cleavage.
