The furfurylphosphonium salts Br (2a-c,e,f) and Br (6) are obtained by reaction of the silylphosphanes RP(SiMe3)2 (1a-c,e), P(SiMe3)3 (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 I (2d) wich results from the reaction of 4f and EtI (eq.(4)).From Ph2PCl (8) and the Grignard compounds ClMg(CH2)2C4(CH3)H2O the bidentate P,O-ligand Ph2P(CH2)2C4(CH3)H2O (9) can also be isolated (eq.(6)), 1H, 31P, and 13C NMR spectroscopic investigations afford an insight into the structures of the novel compounds. - Key words: Tri- and Bidentate Furfurylphosphanes, NMR Investigations
