Description
Potassium (1-naphthalene)trifluoroborate is an aryl potassium trifluoroborate derivative. Potassium aryl trifluoroborate not only has high stability, good crystallinity, but also has the closest reactivity to the corresponding aryl boronic acid, and is the most promising aryl boronic acid derivative for industrial production and application.
Uses
Potassium (1-naphthalene)trifluoroborate is a derivative of arylboronic acid.As a safe and efficient arylation reagent, arylboronic acids have been widely used in the scientific research and development of related fine chemicals such as medicine, pesticide, liquid crystal and OLED optoelectronic materials.
Preparation
1-Naphthaleneboronic acid (0.41 mol), potassium difluoride (0.82 mol), stirred at a high speed of 500 rpm for 10 minutes to obtain a uniformly mixed material, which was continuously added through the feed port of the twin-screw extruder, and the extrusion time Set to 5 minutes, the extruded material is directly received in the receiver containing the same weight of water as the solid material, stirred and dispersed to obtain a slurry, filtered, the filtrate is returned to the receiver, and the filter cake is washed with water and dried with hot air to obtain the product Potassium (1-naphthalene)trifluoroborate.
