    Abstract: The present invention relates to a process for the preparation of furopyrroles of general formula (I), comprising (a) heating a compound of the formula (II) under microwave irradiation optionally in the presence of an inert solvent, wherein A1 and A2 are C1-C18alkyl, C2-C18alkenyl, C2-C18alkynyl, C5-C8cycloalkyl, C5-C8cycloalkenyl, aryl or heteroaryl, A3 is hydrogen, C1-C18alkyl, cyanomethyl, Ar3, —CR30R31—(CH2)m—Ar3 or Y—R32, wherein R30 and R31 independently of each other stand for hydrogen or C1-C4alkyl, or phenyl which can be substitute up to three times with C1-C4alkyl, Ar3 stands for aryl, C5-C8 cloalkyl, C5-C8cycloalkenyl or heteroaryl, which can be substituted one to three times with C1-C9alkyl, C1-C8alkoxy, halogen or phenyl, which can be substituted with C1-C8alkyI or C1-C8alkoxy one to three times, and m stands for 0, 1, 2, 3 or 4, R is C1‘-C18alkyl, in particular C1-C4alkyl, aryl, in particular phenyl, or aralkyl, in particular benzyl, which can be substituted one to three times with C1-C8alkyl, C1-C8alkoxy, or halogen, Y is —C(O)—, —C(O)O—, —C(O)NH—, —SO2NH— or —SO2— and R32 is C1-C18alkyl, Ar3, or aralkyl. The furopyrroles of the general formula (I) can be can be obtained in high yield and high purity by the process of the present invention.

    Abstract: The present invention relates to metal complexes of formula I, compositions comprising the metal complexes, to recording media comprising the metal complexes or compositions and to the use of the compositions in the production of optical recording media: wherein the substituent are, as defined in the description. Use of the metal complexes formula (I) in combination with oxonol dyes results, surprisingly, in a comparatively weak tendency of the oxonol dyes to aggregate in the solid state so that the absorption curve remains advantageously narrow event in the solid state, as a result of which recording media having high reflectivity as well as high sensitivity and good playback characteristics in the desired spectral range are made available.
