[EN] The invention relates to a process for purification of 1-halo-6,6-dimethyl-hept-2-ene-4-yne of Formula (I), wherein X represents a halogen atom subjecting crude 1-halo-6,6-dimethyl-hept-2-ene-4-yne to distillation under reduced pressure to obtain pure 1-halo-6,6-dimethyl-hept-2-ene-4-yne. This compound is an important intermediate for the production of the widely used antifungal drug Terbinafine. [FR] La présente invention concerne un procédé de purification du 1-halogéno-6,6-diméthylhept-2-ène-4-yne de Formule (I), où X représente un atome d'halogène, par soumission du 1-halogéno-6,6-diméthylhept-2-ène-4-yne brut à distillation sous pression réduite pour obtenir le 1-halogéno-6,6-diméthylhept-2-ène-4-yne pur. Ce composé est un intermédiaire important dans la synthèse du médicament antifongique d'utilisation courante Terbinafine.

H/D exchanges of arylmethyl amines and nitrogenheterocycles were conveniently achieved with KOt-Bu/DMSO-d6. The method is also applicable for phenyl benzyl ethers, diarylmethanes, and alkyl arenes. These H/D exchange reactions are suggested to proceed via a free radical pathway.
芳基甲胺和氮杂环的H / D交换可通过KO t -Bu / DMSO- d 6方便地实现。该方法也适用于苯基苄基醚,二芳基甲烷和烷基芳烃。这些H / D交换反应被建议通过自由基途径进行。
