Chemistry of phosphorus ylides 17.1 Reactions with phosphacumulenes X. The behaviour of phosphacumulenes towards o- and p-quinones. Facile synthesis of cyclobutanedione derivatives

Article abstract of DOI:10.1080/10426509608029636

The reactions of the active phosphacumulenes, (2-oxovinylidene)-(7a) and (2-thioxovinylidene)triphenylphosphorane (7b) with several o-(8, 12, 14, 16) and p-quinones (18, 20, 22, 24) have been studied. Phosphoranylidene-cyclobutanediones (11a, 13a, 15a, 17a, 19a, 21a, 23a, 25a) and dithioxocyclobutylidenes (11b, 13b, 15b, 17b, 19b, 21b, 23b, 25b) were obtained and identified on the basis of elemental analysis and spectroscopic studies.
