The reaction of the diphosphide K2[tBuP-(tBuP)2-PtBu] 4 with the halogenostannanes (tBu)2SnCl2, (nBu)2SnCl2, (C6H5)2SnCl2 or nBuSnCl3 in a molar ratio of 1:1 leads via a [4 + 1]-cyclocondensation reaction to the stannatetraphospholanes (tBuP)4SnR2 3b-3d and (tBuP)4Sn(Cl)nBu 3e, respectively, with the binary 5-membered P4Sn ring system. 3b was characterized by a single crystal structure analysis; the 5-membered ring exists in a planar conformation. The compounds 3b-3e were identified by NMR and also by mass spectroscopy; the 31P{1H}-NMR spectra of 3b-3d showed an AA′MM′ (AA′MM′X), 3e on the other hand an ABCD (ABCDX) spin system.
