While the anion of 2-phenyl-lj3-indandione had given with diphenyliodonium chloride in t- butyl alcohol 85% of 2, 2-diphenyl-l, 3-indandione, it gave with dimesityliodonium chloride only 23% of the analogous 2-mesityl-2-phenyl-1, 3-indandione and a small amount of 2-(o- mesitylphenyl)-1, 3-indandione. 2-Mesityl-1, 3-indandione, formed with related products from the anion of 1, 3-indandione and dimesityliodonium chloride, was phenylated on ...
