Syntheses and Structures of Diplatinum Hexatriynediyl Complexes, in Which the sp Carbon Chains Are Shielded by sp3 Carbon Chains
摘要:
When trans, trans-(C6F5)(p-tol(3)P)(2)Pt(Cequivalent toC(3))Pt-(P-p-tol(3))(2)(C6F5) and Ar2P(CH2)(m)PAr2 (m /Ar = 8 / p-tol, 10/ Ph, 11 / Ph, 12 / Ph, 14 / p-tol) are reacted, P-tol(3)P is displaced to give products in which the diphosphines span the platinum end groups. One crystal structure (m = 14) shows a double-helical conformation in which the sp(3) carbon chains twist around the sp chain, and others (m = 10, 11) show nonhelical conformations with lateral shielding of the sp chain.
Disclosed is a composition comprising (A) at least one compound selected from the group consisting of an ether compound having two or more ether groups, a trivalent phosphorus compound, and a ketone compound, (B) a boron trihalide, and (C) an episulfide compound.

similarly yield R2P(CH2)mPR2 (m/R = 8/a, 95%; 14/a, 96%; 14/p-C6H4-t-Bu, 98%). Reactions of KPPh2 with Br(CH2)m′CHCH2and Br(CH2)7CH3 give the corresponding monophosphines Ph2P(CH2)m′CHCH2 (m′ = 7, 82%; 10, 84%) and Ph2P(CH2)7CH3 (85%). When the former is combined with [Pt(μ-Cl)(C6F5)(tht)]2 (tht = tetrahydrothiophene), trans-(C6F5)(Ph2P(CH2)m′CHCH2)2PtCl (77–70%) is isolated. When the latter (excess)
