acyl chloride
Avec des carbones nucléophiles tels que les réactifs de Grignard, les chlorures d'acyle réagissent d'abord une première fois pour donner une cétone, puis réagissent une seconde fois pour donner l'alcool tertiaire équivalent.
Comment obtenir le chlorure d acyle ?
Synthèse.
Le chlorure d'acétyle est synthétisé à partir d'acide acétique que l'on fait réagir avec du chlorure de thionyle : CH3COO-H + O=SCl2 → CH3COCl + SO2 + H-Cl.
Qu'est-ce qu'un chlorure d'acide ?
Le chlorure d'hydrogène (ou l'acide chlorhydrique) est un acide fort totalement dissocié en protons et ions chlorures dans l'eau.
Le chlorure d'hydrogène et ses solutions aqueuses peuvent être à l'origine de réactions dangereuses.
