The reactions of carbodiimides with the iron arylborylene complex [Fe=BDur(CO)3(PMe3)] (Dur=2,3,5,6-Me4C6H) and bis(borylene) [Fe{=BDur}{=BN(SiMe3)2}(CO)3] yield a wide variety temperature-dependent products, including known FeBNC novel FeBNB metallacycles, complexes N-heterocyclic boracarbene spiro-boracarbene ligands unique 1,3,2,4-diazadiborolyl pianostool complex, characterized by NMR spect...

We report an amidinato ligand-supported series of magnesium complexes obtained from the insertion of a magnesium-carbon bond into a carbon-nitrogen double bond of different carbodiimides and α-diimine ligands. The magnesium complexes [Mg(CH2Ph){CyN[double bond, length as m-dash]C(CH2Ph)NCy}]2 (), [Mg(CH2Ph){(i)PrN[double bond, length as m-dash]C(CH2Ph)N(i)Pr}]2 () and the homoleptic [Mg{(t)BuN[...

Although carbodiimides and succinimides are broadly employed for the formation of amide bonds (i.e., in amino acid coupling), their use in the coupling of peptides to water-soluble carboxylic-terminated colloidal gold nanoparticles remains challenging. In this article, we present an optimization study for the successful coupling of the KPQPRPLS peptide to spherical and rodlike colloidal gold na...

Copper-alumanyl complexes, [LCu-Al(SiNDipp)], where L=carbene=NHCiPr (N,N?-diisopropyl-4,5-dimethyl-2-ylidene) and Me2CAAC (1-(2,6-diisopropylphenyl)-3,3,5,5-tetramethyl-pyrrolidin-2-ylidene) featuring unsupported Al?Cu bonds, have been prepared. Divergent reactivity observed with carbodiimides CO2 implies an ambiphilicity in the Cu–Al interaction that is dependent on identity of carbene co-lig...

In all living organisms, all reactions involved in peptides and proteins synthesis proceeds exceedingly efficiently inside the cells in aqueous solution. An approach to efficient preparation of peptides in aqueous media is of great importance because the safe disposal of organic solvents is a vital environmental issue, and even more essential, the aqueous milieu is crucial to preserve the confo...

finite affine groups are given by groups of translations and di-lations on finite cyclic groups. for cyclic groups of prime orderwe develop a time-scale (wavelet) analysis and show that for alarge class of non-zero window signals/vectors, the generatedfull cyclic wavelet system constitutes a frame whose canonicaldual is a cyclic wavelet frame.
