Abstract

Patente de Invenção: <B>"PROCESSO APERFEIçOADO PARA A PREPARAçãO DE MERCAPTOMETILFENóIS"<D>. A presente invenção descreve um processo aperfeiçoado para a preparação de um composto de fórmula I onde n é 0 ou 1, R~ 1~ é C~ 1~-C~ 12~alquila ou -CH~ 2~SR~ 3~, R~ 2~ é C~ 1~-C~ 12~alquila, C~ 7~-C~ 9~fenilalquila, C~ 7~-C~ 9~fenilalquila substituída no radical fenila por 1 a 3 grupos C~ 1~-C~ 4~alquila; ou -CH~ 2~SR~ 3~, R~ 3~ é C~ 6~-C~ 18~alquila, fenila ou benzila, R~ 4~ é hidrogênio ou metila, R~ 5~ é hidrogênio ou metila, com a condição de que R~ 4~ e R~ 5~ não sejam simultaneamente metila, através de reação de um composto de fórmula II onde n, R~ 4~ e R~ 5~ são como anteriormente definido, R~ 11~ é hidrogênio ou C~ 1~-C~ 12~alquila; e R~ 12~ é hidrogênio, C~ 1~-C~ 12~alquila, C~ 7~-C~ 9~fenilalquila, C~ 7~-C~ 9~fenilalquila substituída no radical fenila por 1 a 3 grupos C~ 1~-C~ 4~alquila, com formaldeído ou um composto que libera formaldeído sob as condições de reação e com pelo menos um composto de fórmula III. R~ 3~SH onde R~ 3~ é como anteriormente definido, na presença de uma base, sendo a base mono ou dimetilamina ou mono ou dietilamina, processo este que compreende tratar em seguida o produto de reação com um agente de redução.
