Stereochemistry of the enzymic lactonisation of cis,cis-muconic and 3-methyl-cis,cis-muconic acid

Journal of the Chemical Society, Perkin Transactions 1, 1996
Experiments with 4-methyl[3,5,6-2H3]pyrocatechol 7 have shown that the product of its enzymic oxygenation, 3-methyl-cis,cis-muconic acid 8, undergoes enzymic cyclisation by syn addition of carboxy groups to distal double bonds to form the (S)-4-methylmuconolactone 9 in the bacterium Pseudomonas putida and the (S)-3-methylmuconolactone 11 in the fungus ...

iCI: Iterative CI toward full CI

Journal of Chemical Theory and Computation, 2016
It is shown both theoretically and numerically that the minimal multireference configuration interaction (CI) approach [Liu, W.; Hoffmann, M. R. Theor. Chem. Acc. 2014, 133, 1481] converges quickly and monotonically from above to full CI by updating the primary, external, and secondary states that describe the respective static, dynamic, and again ...

cis,cis,cis-1,5,9-Cyclododecatriene−Metal Complexes

Organometallics, 2007
The ligand properties of cis,cis,cis-1,5,9-cyclododecatriene (c,c,c-cdt) have been explored. For the known (c,c,c-cdt)Ni (1b) and (c,c,c-cdt)(AgNO3)3 (5) complexes and the new [(c,c,c-cdt)Cu(MeOH)]BF4 (6b), [(c,c,c-cdt)Cu][Al{OC(CF3)3}4] (6d), and (tBu2PC2H4PtBu2)Ni(η2-c,c,c-cdt) (7b) complexes, the molecular structures have been determined.

CI Implementation: An Empirical Test of the CI Maturity Model

Creativity and Innovation Management, 2006
There are a number of tools available for organizations wishing to measure and subsequently develop Continuous Improvement (CI). In this article, we review and evaluate a well‐accepted CI development model, namely the CI Maturity Model (Bessant and Caffyn, 1997), against data collected from the 2nd Continuous Improvement Network Survey and a number of ...

?????????????????? ???????????????????????????????? ?????????????? ?????????????? ???????????????????? ????????: CF???CI??? ?? CHF???CI

2021
The isochoric thermal conductivity and the thermal pressure of solid freons of a methane series CF???CI??? and CHF???CI are studied near the melting temperature. It is found that the isochoric thermal conductivity of CHF???CI increases slowly with temperature whereas in the case of CF???CI??? it is practically constant.
