FIELD: organic chemistry.
SUBSTANCE: method for preparation of (E)-2-(3-(1H-pyrrol-2-yl)allylidene)-1H-indan-1,3(2H)-dione derivatives of the general formula Ia-d. The method is carried out by boiling substituted (E)-3-(1H-pyrrol-2-yl) acrylic aldehydes of formula IIa-e with indanedione of formula III in ethyl alcohol in the presence of an organic base, followed by purification in accordance with the given scheme.
EFFECT: obtaining a series of (E)-2-(3-(1H-pyrrol-2-yl)allylidene)-1H-indan-1,3(2H)-dione derivatives of general formula Ia-e, which can be used in photovoltaics as photosensitizers for solar cells.
