    摘要:
    合成了一系列碱稳定的甲硅烷基物质,并探索了它们对CO 2的反应性,从而表征了一种新型的N / Si + FLP-CO 2加合物。这些硅物质是用9-BBN,儿茶酚硼烷(catBH)和频哪醇硼烷(pinBH)将CO 2加氢硼化至甲醇盐水平的活性催化剂。实验和DFT计算都突出了FLP-CO 2加合物在催化中的作用。根据氢硼烷还原剂的性质,揭示了两种不同的机理。9-BBN和catBH能够还原中间的FLP-CO 2加合物,而CO 2的硼氢化与pinBH一起走的是另一条新颖的途径,其中B–H键被基于硅的路易斯酸催化剂活化。在这些机理中,发现高度稳定的FLP-CO 2加合物的形成不利于反应动力学。

  • Bicyclic Guanidinates in Mono- and Di-Valent Metal Complexes, Including Group 1/2 and Group 1/12 Heterometallic Systems
    作者:Martyn P. Coles、Peter B. Hitchcock
    DOI:10.1071/ch12560
    日期:——

    Complexes containing mono-, di-, and mixed mono-/di-valent metal centres supported by the [hpp]– anion (hppH = 1,3,4,6,7,8-hexahydro-2H-pyrimido[1,2-a]pyrimidine) are reported. Amine elimination from Mn(NSiMe3}2)2 using the neutral guanidine is a clean route to the heteroleptic compound [Mn(hpp)(NSiMe3}2)]2. Addition of 18-crown-6 to a solution of the hpp– potassium salt (hppK) enables the first potassium derivative of [hpp]– to be structurally analysed, showing that the crown ether restricts aggregation to afford a monometallic structure. Mixed lithium–magnesium and lithium–zinc compounds of general formula Li2M2(hpp)6 (M = Mg, Zn) have been characterised crystallographically showing the guanidinate anions to be present in two different coordination modes, bridging two- or four-metal centres. Spectroscopic measurements suggest a robust framework that is maintained in solution.

    Monoalkyl uranium chemistry has been probed by reacting the metallocene chloride complex (C5Me5)(2)(hpp)UCl, 1, (hpp)(-) = 1,3,4,6,7,8-hexahydro-2H-pyrimido[1,2-a]pyrimidinato, with alkyl lithium reagents. Complex I reacts with LiMe, LiC equivalent to CPh, LiPh, and LiEt to generate (C5Me5)(2)(hpp)UMe, 2, (C5Me5),(hpp)U(C equivalent to CPh), 3, (C5Me5)(2)(hpp)UPh, 4, and (C5Me5)(2)(hpp)UEt, 5, respectively. Complexes 2-5 react with Cul to form the iodide complex (C5Me5)(7)(hpp)UI, 6, and methane, phenylacetylene, benzene, and ethane, respectively. Attempts to make a neopentyl analogue of 2-5 from the reaction of 1 with neopentyllithium yielded the "tuck-in" complex (C5Me5)(eta(5):eta(1)-C5Me4CH2)(hpp)U, 7. Complex 7 can also be synthesized by heating 5 to 70 degrees C in a reaction that forms ethane as a byproduct.

    Tetrabutylammonium chloride and nitrate salts react with (C5Me5)(2)UCl2 to expand the coordination sphere of the metallocene to form the formal 9- and 10-coordinate complexes, [NBu4][(C5Me5)(2)UCl2(NO3)], 1, and [NBu4][(C5Me5)(2)UCl2(NO3)], 2, respectively. Complex 2 displays modified reactivity compared to that of (C5Me5)(2)UCl2 in substitution reactions with Khpp [hpp = 1,3,4,6,7,8-hexahydro-2H-pyrimido(1,2-a)pyrimidine] and K(NC4Me4) in the synthesis of (C5Me5)(2)U(hpp)Cl, (C5Me5)U(hpp)(3), and (C5Me5)(2)U(NC4Me4)Cl. The U3+ complex, [NBu4][(C5Me5)(2)UCl2], can be formed by reduction of 2 with K(Hg), as well as with KC5Me5, K2C8H8, and Li3N.
