NEW MATERIAL:An indoline compound expressed by formula I (R<1> and R<2> are 1-10C alkyl; R<3> and R<4> are hydroxy, amino, organic substituted amino, 1-4C alkoxy, 7-15C aralkoxy, 6-14C aryloxy, 1-4C alkyl, halogen, cyano, carboxy, 2-10C alkoxycarbonyl, 2-10C acyl, 1-4C halogen-substituted alkyl or nitro; l is 1-5; m is 0-4; n is 1-4). EXAMPLE:1-(2,3,4,5,6-Pentafluorobenzyl)-3,3-dimethyl-2-methylindoline. USE:Useful as an intermediate raw material for spiro compounds used as photochromic compounds, optical charge generating substances, physiologically active substances, etc., or as photoconductive layer forming substances of electrophotographic sensitive materials. PREPARATION:A reaction product of a compound expressed by formula II with a compound expressed by formula III (X is anionic eliminative group) is without isolation reacted with a basic substance to afford the aimed compound expressed by formula I. |
