The relative configuration of 3-(2,3-dihydro-1H-indenyl)methyloxopropyl 4-bromobenzoate was assigned by X-ray crystal structure analysis, allowing additional insights into the mechanism of the thallium(III)-promoted oxidative rearrangement of homoallylic alcohols. The reaction of primary homoallylic alcohols bearing the electron Cited by: 8. Revered as the standard reference for chemists for more than 60 years, this new edition of Lange's brings chemistry professionals, students, and anyone interested in science an enormous compilation of facts, data, tabular material, and experimental findings in every area of chemistry.
The oxidation of 1 and 6 yielded the endo- and exoalcohols 2a, 2b, 7a, and 7b, respectively, with minor amounts of the 3-alcohols 3 and 8. 5 The radical rearrangement products of each probe (5 and 10) formed in substantial yield, representing 62 % of the product in the case of by: 1.)

The structure of this imine is confirmed by alkaline hydrolysis to give mainly 1,2-dihydro-1,4-dimethyloxo-pyrimidine, which differed from the known 1,6-dimethyl isomer; the minor products are 4-methylmethyl-aminopyrimidine, formed from the imine by very slow Dimroth rearrangement, and 2-hydroxymethylpyrimidine.
2-Aminobromo(or. Tartaric acid is an ideal asymmetric catalyst as it is abundant, cheap, and environmentally friendly. (+)-Tartaric acid was found to catalyze a novel enantioselective [4 + 2] cycloaddition of isochromene acetals and vinylboronates. A variety of substituted 1-dimethyl-2-oxo-1 acetals were tolerated, furnishing the desired dihydronaphthalenes and dihydrobenzofluorene products in Cited by: The photochemical rearrangement of 1,2-dihydronaphthalenes into 1,4-dihydronaphthalenes induced by amines Article September with 11 Reads How we measure 'reads'.

The photochemistry of 1,2-dihydronaphthalene oxide was studied in order to determine the pathway by which rearrangement to ring-contracted products occurs. The amounts of indan were found to be the same in both acetonitrile and 1,4-dioxane which suggests that the process is diradical and not by: 4.

1, 2-Dihydro-1, 1, 6-trimethylnaphthalene is isolated from strawberry oil, peaches, tobacco and wines. 1, 2-Dihydro-1, 1, 6-trimethylnaphthalene is a component of wine off-flavour on ageing. The enzymatic formation of naphthalene hydrates (i.e. 1-hydroxy-1,2-dihydronaphthalene and 2-hydroxy-1,2-dihydronaphthalene) was evidenced by comparing their UV and mass spectral data as well as their chromatographic properties (GC, HPLC) with those of the prepared standards ().A separation of the hydrates by HPLC could be achieved and the individual isomers were Cited by: 7.
The usu 1 reaction t1 e for t he dienone-phenol rearrangement varies from ix to twelve hours. Whon 1,1 dimethyloxo-1,2-dihydronaphth lene (VI) w a llowed to stand eighteen hours in the presence of acetic anhfdride and sulfuric acid, it gave only a trace of the rearranged product.
