Abstract

Задача настоящего изобретения заключается в разработке способа, согласно которому можно получить высокий процент выхода Z-1,2-диарил-аллилхлоридов общей формулы(I)применяемых в качестве промежуточных продуктов при получении фармакологических, фунгицидных и противогрибковых действующих начал.Способ стереоизбирательного получения веществ общей формулы (I) заключается в том, что хлоргидрины формулы (II)где остатки R1 и R2 независимо друг от друга означают водород, галоген, алкил, галогеналкил, алкокси, галогеналкокси или незамещенный или замещенный ароматический остаток, а n и m означают 1, 2 или 3, дегидратируют в инертном простом эфире или сложном эфире карбоновой кислоты в качестве растворителя в присутствии ангидрида карбоновой кислоты или соответствующего кетена и органической или неорганической кислоты или олеума при температурах до 50оС.
