The furfurylphosphonium salts [RP(CH2C4H2O3]Br (2a-c, e, f) [R = Ph (a). Mes (b). Me (c), t-Bu (e), CH7C4H3O (f)] and [Ph2P(CH2C4H3O)2]Br (6) are obtained by reaction of the silvlphosphanes RP(SiMe3)2 (1a-c, e). P(SiMe3), (3) and Ph2PSiMe3 (5) with BrCH2C4H3O (eq. (1). (2) and (5)). In THF 2a-c, e, f and 6 are degraded by LiAlH4 to give the tri- and bidentate alkyl and aryl furfurylphosphanes RP(CH2C4H3O)2 (4a-c, e, f) and Ph2PCH2C4H3O (7). respectively (eq. (3) and (5)). The formation of EtP(CH2C4H3O)2 (4d) succeeds via degradation of the phosphonium salt [EtP(CH2C4H3O)3]I (2d) which results from the reaction of 4f and EtI (eq. (4)). From Ph2PCI (8) and the Grignard compound ClMg(CH2)2C4(CH3)H2O the bidentate P,O-ligand Ph2P(CH2)2C4(CH3)H2O (9) can also be isolated (eq.'(6)), 1H, 31P{1H}, and 13C{1H} NMR spectroscopic investigations afford an insight into the structures of the novel compounds.

Keywords: Tri- and Bidentate Furfurylphosphanes; NMR Investigations
