Soluble silica reduces aluminum availability and ameliorates toxicity in several biological systems. It has therefore been suggested that these two species strongly interact in solution. However, there is only weak affinity between monomeric silicic

The migratory insertion reaction of NO into the Co−CH3 σ-bond in the cobalt cyclopentadienyl complex CpCo(NO)(CH3) (2), both with and without the assistance of an incoming ligand (PH3, 1), has been studied using ab initio molecular orbital and den

Recent kinetic measurements of the oxidation of linoleic acid by soybean lipoxygenase show that the thermal rate constants, kH ) 280 ((12) s -1 and kD ) 5.0 ((0.1) s -1 , are weakly temperature dependent within the temperature interval 30-50 °C. The

Photolyses of 2,3-bis(trimethylsilyl)-substituted methylenecyclobutenones 22−26 give essentially quantitative conversion to the allenylketenes 28−32 which have been isolated as long-lived species at room temperature. As predicted by molecular orb

The first examples of crystallographically characterizable complexes of Tb(2+), Pr(2+), Gd(2+), and Lu(2+) have been isolated, which demonstrate that Ln(2+) ions are accessible in soluble molecules for all of the lanthanides except radioactive promet

[N3N]TaPPh ([N3N]3- = [(Me3SiNCH2CH2)3N]3-) reacts with excess lithium metal in tetrahydrofuran to give “[N3N]TaPLi”, as judged by NMR studies and by reactions with RX at −35 °C to afford the phosphinidene complexes [N3N]TaPR (R = Me, n-Bu, Si

Photostimulated additions of tert-butylmercury halides to 1,6-dienes and enynes, including (CH2CHCH2)2X with X = CH2, C(COEt)2, O, or NCH2CHCH2, form the primary alkylmercury halides resulting from 5-exo-cyclizations of the adduct radicals, t-BuCH2CH

Computational predictions of planar tetracoordinate carbon R1R2CαLi2 arrangements in the cyclopropenyllithium dimer have now been realized experimentally in derivatives with additional chelating ligands. The dimer structures of two substituted cyclo

In this work, a novel NMR method for the identification of preferential coordination sites between physiologically relevant counterions and nucleic acid bases is demonstrated. In this approach, the NMR cross-correlated relaxation rates between the ar
