Abstract: 1-Methyl-3-halophenylindanes of formula (I) useful as intermediates for the prepn. of dyes and parasiticides, and dihalo-1-methyl-3-phenylindanes of formula (II), are prepd. by reacting a mixt. of a styrene of formula (II), are prepd. halostyrene of formula (IV) in the presence of phosphoric acid having a concn. of >=75% and opt. of org. cpds. absorbing light between 2000 and 8000 A, or by a similar reaction using halostyrenes of formula (IV) as starting materials. (where R1, R2 and R3 are each H, or alkyl, and R4 is halogen) (I) and (II) are given in good yields and method is commercially possible.

Abstract: The invention concerns benzene derivatives of the formula (I) in which n is 0, 1, or 2, X is nitro or amino, Z is a direct bond or optionally substituted alkylene, Y is vinyl or a group of the formula C2H4-Q in which Q is hydroxy or a group which can be split off under alkaline reaction conditions, R and R are hydrogen, C1-C4 alkyl, C1-C4 alkoxy, halogen, nitro, amino, hydroxysulphonyl or a group Z-SOn-Y in which n, Z and Y are as defined above and Het is a heterocyclic ring. Such benzene derivatives are suitable for use in the production of dyes.
