Abstract
The 4,5-diformyl-1,3-dithiol-2-ylidene ethanals and ethanones 4 are pr epared by a three-step sequence from acetylenedicarbaldehyde mono-diEt -acetal and 3-thioxo-1,2-dithioles. Their X-ray diffraction structure, H-1 nmr and IR properties, reveal a delta-cis conformation in the sol id state and in solution, due to strong S...O 1,5-internal bonding int eractions.
