An ion pair scandium hydride supported by a dianionic (NNNN)-type macrocycle ligand.
A scandium hydride supported by a (NNNN)-type macrocycle consists of a trinuclear cation and a trinuclear anion. The anion shows significantly higher reactivity.
متن کاملN ov 2 00 8 arXiv : 08 mm . nnnn [ hep - ph ] Doubly - Charged Boson Production in pp̄
It is suggested that the observed excess of muons in studies of pp̄ collisions at √ s = 1.96 TeV arises from the decay of doubly-charged bosons. Such particles are predicted in the 3-3-1 model where the electroweak gauge group is extended to SU(3)× U(1). ∗[email protected]
متن کاملModular construction of extended DNA recognition surfaces: mutant DNA-binding domains of the 434 repressor as building blocks.
Single-chain derivatives of the 434 repressor containing one wild-type and one mutant DNA-binding domain recognize the general operator ACAA-6 base pairs-NNNN, where the ACAA operator subsite is contacted by the wild-type and the NNNN tetramer by the mutant domain. The DNA-binding specificities of several single-chain mutants were studied in detail and the optimal subsites of the mutant domains...
متن کاملScandium alkyl and amide complexes containing a cyclen-derived (NNNN) macrocyclic ligand: synthesis, structure and ring-opening polymerization activity toward lactide monomers.
Cyclic polyamine 1,4,7-trimethyl-1,4,7,10-tetraazacyclododecane, (Me(3)TACD)H (= Me(3)[12]aneN(4)), reacted with [K{N(SiHMe(2))(2)}] in benzene-d(6) to give [K{(Me(3)TACD)SiMe(2)N(SiHMe(2))}] (1) under hydrogen evolution. Single-crystal X-ray diffraction of 1 shows a dinuclear structure in the solid state, featuring a bridging μ-amido and a weak β-agostic Si-H bond. 1,7-Dimethyl-1,4,7,10-tetraa...
متن کاملIsolation of altered specificity mutants of the single-chain 434 repressor that recognize asymmetric DNA sequences containing the TTAA and TTAC subsites.
A novel single-chain (sc) protein framework containing covalently dimerized DNA-binding domains (DBD) of the phage 434 repressor was used to construct combinatorial mutant libraries in order to isolate mutant DBDs with altered specificities. The library members contain one wild-type DBD and one mutant domain with randomized amino acids in the DNA-contacting region. Based on previous studies, th...
