SYNTHESES OF A NEW CLASS OF DYES - COUPLING REACTIONS OF DIAZONIUM SALTS WITH 2- AND 3-ALKOXY-1,6-METHANO--ANNULENES
2- and 3-alkoxy-1,6-methano--annulenes were coupled with aryldiazonium salts yielding the corresponding quinone hydrazones as cycloheptatriene derivatives.Analytical data are discussed.
