Abstract

A series of acenaphthene species with a diisopropylphosphino group and a variety of bismuth functionalities in the peri-positions were synthesised and fully characterised, including single crystal X–ray diffraction. The majority of the reported species feature a relatively rare interpnictogen P−Bi bond. The series includes the phosphine¬−bismuthine, Acenap(PiPr₂)(BiPh₂) 2 (Acenap = acenaphthene-5,6-diyl), which was subjected to a fluorodearylation reaction to produce Acenap(PiPr₂)(BiPhX) 5−8 and 10 (X = BF₄^-, Cl, Br, I, SPh), displaying varying degrees of ionicity. The geminally bis(acenaphthyl) substituted [Acenap(PiPr₂)₂]BiPh 3 shows a large through-space coupling of 17.8 Hz, formally ^8TS_JPP. Coupling deformation density (CDD) calculations confirm the double through-space coupling pathway, in which the P and Bi lone pairs mediate communication between the two ³¹P nuclei. Several synthetic routes towards the phosphine−diiodobismuthine Acenap(PiPr₂)(BiI₂) 9 have been investigated, however the purity of this, surprisingly thermally stable potential synthon, remains poor.
