## Abstract The 3,3‐dichloro‐2,2,4,4‐tetramethylcyclobutanethione (**4b**) was prepared from the parent diketone by successive reaction with PCl~5~ and __Lawesson__ reagent in pyridine. This new thioketone **4b** was transformed into 1‐chlorocyclobutanesulfanyl chloride **5** and chloro 1‐chlorocyc
QUIPHOS-PN5, a new stable P,N ligand with a stereogenic phosphorus centre was synthesised in two steps from 8-bromoquinoline (61% yield). Its structure and its bidentate chelating ability was confirmed by the X-ray structure of a palladium(II) complex with this ligand. P(V) derivatives of QUIPHOS-PN
