COLORING COMPOSITION AND RECORDING METHOD

PROBLEM TO BE SOLVED: To provide a coloring composition that can form an image having silver gloss. SOLUTION: A coloring composition contains a stilbene compound represented by general formula (1), and two or more solvents. For the two or more solvents, a

Organometallic Compounds: Part I - Reduction of Benzophenones, 4,4'-Dialkoxydeoxybezoins, Benzils and Chalkones with Cyclohexylmethylmagnesium Bromide

Cyclohexylmethylmagnesium bromide (I) reduces benzophenones (IIa-e) when reacted in a molar ratio of 4:1, to give mainly the corresponding benzhydrols (IIIa-e).A similar reaction of I with 4,4'-dialkoxydeoxybenzoins (IIf,g) results in the formation of carbinols (IIIf,g), the dehydration of which gives the corresponding stilbenes (VIIa,b).However, when benzil (IXa) (1 mol) is treated with I (4 mol), both reduction and addition reactions take place giving rise to a mixture of benzoin (Xa) and the addition product (IXa).A similar reaction of I with 4,4'-dimethoxybenzil (IXb) gives the addition product (XIb) together with anisic acid.
