The tert ‐butyl‐substituted arsa‐ and stibaphosphanes t Bu 2 EP(H) t Bu ( 1 : E = As, 2 : E = Sb) were prepared by lithium chloride salt elimination. Metalation of 1 and 2 with n BuLi yielded the Li 2 P 2 ring compounds [ t Bu 2 EP(Li · OEt 2 ) t Bu] 2 ( 3 : E = As, 4 : E = Sb). By reaction of t Bu 2 ECl (E = As, Sb) with 3 and 4 , the interpnictogen chain molecules ( t Bu 2 E) 2 P t Bu ( 5 : E = As, 6 : E = Sb) as well as t Bu 2 SbP( t Bu)As t Bu 2 ( 7 ) are accessible. Compound 7 is the first crystallographically characterized molecule in which a phosphorus atom is bound to both arsenic and antimony. Compounds 3 – 7 were characterized by single‐crystal XRD, NMR spectroscopy, IR spectroscopy and mass spectrometry.
