Choix des methodes pour la synthese univoque de carbures acetyleniques. Troisieme partie : Arylacetylenes et aryl-1 alcynes-1
The range of applicability of six syntheses of pure alkynes with one aryl group has been defined; a short review of other possible procedures is included.We have specified the best method to obtain selectively the alkynes Ar-CCH and Ar-CC-R, according to the nature of the substituents of the aryl group and according to the developed structure of the R group.It is thus possible to recommend with the largest probability of success the method to obtain, in homogenous series, alkynes corresponding to still more complicated structures.
An approach to the synthesis of unsymmetrically substituted chlorobiphenyls
The Diels-Alder cycloaddition of o-chloranil with phenylacetylenes substituted with chlorine in the ring can afford chlorobiphenyls upon photodecomposition of the brodged diketone adduct.Biphenyls derived from 3-chloro-, 4-chloro-, 2,4-dichloro-, and (2,5
