  Synthesis and reactions of 1,3-bis(diphenylphosphino-κP)-2-methylallyl complexes of platinum

  摘要：

  Treatment of [PtX2(cod)] (cod = cycloocta-1,5-diene) with the diphosphine (Ph2PCH2)2C=CH2 gives the complexes [PtX2{(Ph2PCH2)2C=CH2}] (X = Cl 1a or Me 1c). The dichloro complex can be converted to give the corresponding diiodo complex by metathesis and isomerised by base (NaOH-EtOH) to give [PtCl2(Ph2PCH2CMe=CHPPh2)] 2a. Treatment of complexes 1a, 1c or 2a with LiMe gives [PtMe2{(Ph2PCH)2CMe)]- 3, containing a symmetrical anionic diphosphine, which reacts with MeOH to give [PtMe2(Ph2PCH2CMe=CHPPh2)] 2b. Treatment of 1a or 2a with equimolar amounts of Cl2 produces the corresponding tetrachloroplatinum(IV) complexes 4 and 5, whilst treatment of 1c with Mel gives [PtMe3I{(Ph2PCH2)2C=CH2}] 6; 4-6 are all unstable in solution with respect to reductive elimination reactions, 4 and 5 giving 1a and 2a respectively whilst 6 gives [PtMel{PhPCH2)2C=CH2}]. Treatment of 3 with electrophilic reagents such as Mel, PhCH2Br, SiMe3Cl or PPh2Cl gives complexes [PtMe2(Ph2PCHRCMe=CHPPh2)] (R = Me 7a, PhCH2 7b, SiMe, 7c or PPh2 7d). Treatment of the salt [Pt{(Ph2PCH2)2C=CH2}2]Cl2 9 with NaBH, gives the platinum(o) compound [Pt{(Ph2PCH2)2C=CH2}2] 9, whilst with LiBu-Me2NCH2CH2NMe2 it gives the unusual platinum(II) complex [Pt{Ph2PCH2C(=CH2)CHPPh2}2] 10, in which the Pt is bonded to two P and two C atoms and two of the phosphorus atoms are uncomplexed.
