Popis:	5-Arylidenerhodanines and the previously undescribed 5-[5-(4-R-phenyl)furfurylidene]rhodanines were synthesized by the Andreasch method. It is assumed that Fermi resonance appears in the IR spectra of some of these compounds in the region of carbonyl absorption; bands of associated N-H bonds were identified. It is shown that in the case of 4-N(CH3)2-benzylidenerhodanine the long-wave band in the electronic spectra is a bathochromically shifted band of the same nature as the band in the spectra of 5-arylidenerhodanine derivatives with weak donor groups. The introduction of an arylfurfurylidene grouping gives rise to a substantial bathochromic shift of the absorption band of their molecules.
