Abstract
The invention comprises 1 - phenyl - 3,3 - dimethyl - spiro[(21H - 11 - benzopyran) - 2,21 indoline] having the structure <FORM:0883803/IV (b)/1> and its derivatives having the structure <FORM:0883803/IV (b)/2> in which R1, R2 and R3 represent stericall compatible substituents attached to one or more of the unoccupied positions of the benzene rings selected from CH3, CH2CH3, CH(CH3)2, C(CH3)3, C6H5, CF3, CN, COCH3, COOC2H5, COOH, NH2, NHCH3, N(CH3)2, NHCOCH3, NO2, OCH3, OC2H5, O(CH2)2CH3, O(C6H5), OH, OCOCH3, SCH3, SH, SCOCH3, SCN, SOCH3, SO2CH3, SO2NH2, F, Cl, Br, I, IO2, CH2CH= CH2, and COOCH3. These compounds may be prepared by condensing 1-phenyl-3,3-dimethyl-2-methyleneindoline or a suitably substituted derivative thereof with salicylaldehyde or a suitably substituted derivative thereof. Preferably the reactants are dissolved in ethanol and refluxed until the required compound appears in solid form. Examples are given of the p preparation of 1 - phenyl - 3.3 - dimethyl - spiro[(21H - 11- benzopyran)-2,21-indoline] without substituents and containing as substituents (a) an NO2 group in the 61 position or OCH3 in the 81 position; (b) an NO2 group in the 61 position and (c) NO2 groups in the 61 and 81 positions by condensing 1-phenyl-3,3-dimethyl-2-methyllene indoline with salicylaldehyde, 3-methoxy5 - nitrosalicylaldehyde, 5 - nitrosalicylaldehyde and 3.5-dinitrosalicylaldehyde respectively. A compound having chlorine radicals in the 5,7,211 and 411 positions is obtained by condensing salicylaldehyde with 1 - (2,4 - dichlorophenyl) - 3,3 - dimethyl - 2 - methylene - 5,7 - dichloroindolene. 1 - Phenyl - 3,3 - dimethyl - 2 - methylene indoline used as starting material may be prepared by (a) treating N-nitro diphenylamine with zinc dust and with hydrochloric acid to give N,N-diphenyl hydrazine hydrochloride, (b) condensing the diphenyl hydrazine hydrochloride with methyl isopropyl ketone to form the N,N-diphenyl hydrazone of methyl isopropyl ketone and (c) treating the hydrazone with zinc chloride to give the required 1-phenyl-3,3-dimethyl-2-methylene indoline. To get a substituted 1-phenyl-3.3-dimethyl-2-methylene indoline the correspondingly substituted diphenylamine is used as starting material. For example to obtain 1-(2,4-dichlorophenyl) - 3,3 - dimethyl - 2 - methylene - 5,7 - dichloroindoline 2,4,21,41 - tetrachloro diphenylamine is used as starting material.
