摘要：

The behavior of the reactive phosphacumulenes 2a,b, towards different alpha-diketone monohydrazones 1, 5, 11, and 13, acenaphthenequinone monohydrazone 8 and indantrione monohydrazone 16 has been studied. In some cases the resulted phosphoranes directly cyclize by an intramolecular Wittig reaction with the formation of pyridazinones 4a, 6, 9, 12, and 17 and pyridanzinethione 4b. Structure of the new products were assigned according to consistent analytical and spectroscopic data.
