Abstract

Раскрывается способ получения (гало)фторуглеводорода, который включает нагревание альфа-фторэфира в паровой фазе при повышенной температуре. альфа-фторэфиры получают реакцией не-енолизируемого альдегида с фторводородом, чтобы образовать промежуточное соединение, и реакцией промежуточного соединения со спиртом или галогенирующим агентом. Предлагаются также новые альфа-фторэфиры.
