Highly Efficient Microwave‐Assisted Synthesis of Subphthalocyanines

Abstract

A novel, highly efficient, single‐step synthesis of subphthalocyanines using microwave irradiation of phthalonitrile and boron trichloride in 1‐chloronaphthalene was accomplished for the first time. This provides a new preparative method for the synthesis of subphthalocyanines with reduced reaction times and improved yields.

Keywords:

• boron trichloride
