Preparation, thermolysis, and photolysis of 2-diazo-1,3-dimesityl-2H-indene: a sterically stabilised 2-diazoindene
Abstract
2-Diazo-1,3-dimesityl-2H-indene (2) is prepared by reaction of 2-amino-1,3-dimesityl-2H-indene with sodium nitrite–acetic acid; though isolable (2) decomposes either thermally (20 ° C) or on exposure to visible light to give the hydrocarbons (6), (7), and (8) derived via the carbene (9) and the o-quinodimethane (10).
