Mechanistic investigations of the Fe(ii) mediated synthesis of squaraines.

The scission and homologation of CO is a fundamental process in the Fischer-Tropsch reaction. However, given the heterogeneous nature of the catalyst and forcing reaction conditions, it is difficult to determine the intermediates of this reaction. Here we report detailed mechanistic insight into the scission/homologation of CO by two-coordinate iron terphenyl complexes.

Nucleophilic Fluorination Catalyzed by a Cyclometallated Rhodium Complex.

Quantitative catalytic nucleophilic fluorination of a range of acyl chlorides to acyl fluorides was promoted by a cyclometallated rhodium complex [(η,κC-CMeCHCFCHNCHNMe)- RhCl] (). can be prepared in high yields from commercially available starting materials using a one-pot method. The catalyst could be separated, regenerated, and reused.

Conversion of haloform to carbonate by iridium N-heterocyclic carbene complexes and silver(i) oxide.

The reaction between haloform, the complexes [Cp*IrCl2(κC-MeNC3H2NCH2Ar)] (Ar = C6H3F2-2,6, C6H3F-2-Cl-6, C6H3Me2-2,6) and silver(i) oxide proceeded by carbon-halogen bond fission to yield the carbonate complexes [Cp*Ir(κ2O-CO3)(κC-MeNC3H2NCH2Ar)].

Lower Extremity Strength Is Correlated with Walking Function After Incomplete SCI.

Background: Lower extremity strength has been reported to relate to walking ability, however, the relationship between voluntary lower extremity muscle function as measured by isokinetic dynamometry and walking have not been thoroughly examined in individuals with incomplete spinal cord injury (iSCI).

Objective: To determine the extent to which measures of maximal voluntary isometric contraction (MVIC) and rate of torque development (RTD) in the knee extensor (KE) and plantar flexor (PF) muscle groups correlate with self-selected overground walking speed and spatiotemporal characteristics of walking.

Methods: Twenty-two subjects with chronic (>6 months) iSCI participated in a cross-sectional study.
