PROCESS FOR THE PREPARATION OF META-ARYLOXYBENZALDEHYDES, AND META- ARYLOXYBENZALDEHYDES PRODUCED BY THE PROCESS |
摘要 |
Process for the preparation of meta-aryloxybenzaldehydes, especially meta-phenoxybenzaldehyde, which comprises reacting a mixture of meta-aryloxybenzyl and meta-aryloxybenzal halides with hexamethylenetetramine and hydrolysing the resulting product in the presence of a non-acidic solvent. Meta-phenoxy benzaldehyde is an important intermediate in the manufacture of a group of insecticidally-active compounds known as pyrethroids. |
