intermolecular reaction造句

例句与造句

1. The compound gets cycled and forms inosinate after a sort of intermolecular reactions.
2. That is to say an intramolecular reaction is faster than its corresponding intermolecular reaction.
3. The inherent difficulties of controlling enantioselectivity in intermolecular reactions made the development of an intermolecular asymmetric Stetter reaction a challenge.
4. Exchange reactions involve the substitution of one reaction partner in an intermolecular reaction for another with an identical type of bonding.
5. After release of nitrogen gas and conversion to the metallocarbene, an intermolecular reaction with a carbonyl group can generate the carbonyl ylide.
6. It's difficult to find intermolecular reaction in a sentence. 用intermolecular reaction造句挺难的
7. This creates a very high effective concentration ( resulting in high reaction rates ), and, therefore, many intramolecular reactions that would not occur as an intermolecular reaction between two compounds take place.
8. The reaction mechanism as proposed by the Barbas group in 2000 for the intermolecular reactions is based also on enamine formation and the observed stereoselectivity based on the Zimmerman-Traxler model favoring Re face approach.
9. Although the opportunity for intermolecular reactions can increase as the polymer chains grow, the likelihood of this occurring at the early stage of reactions is minimal due to the low chain concentration, which is why single chain cyclized / knotted polymers can form.
10. He has used the coordination chemistry of Zn, Sn, Ru, Rh and Al oligoporphyrins A cyclic metallo-porphyrin tetramer created by templated synthesis around a fifth porphyrin to create new complex systems, to develop new templated approaches in synthesis, and to engineer the acceleration of intermolecular reactions within host cavities.
11. The intermolecular reaction of the hydroxy-pyrone and ?, ? unsaturated ester shown below suffered from poor yield and regioselectivity; however, when directed by phenylboronic acid the desired adduct could be obtained in 61 % yield after cleavage of the boronate with 2, 2-dimethyl-1, 3-propanediol.
12. Ziegler s synthetic method, which included running reactions at high dilution to favor the intramolecular cyclization over competing intermolecular reactions, resulted in yields superior to those of existing procedures ( Laylin ) : he was able to prepare large-ringed alicyclic ketones, C 14 to C 33, in yields of 60 80 %.
13. This relationship means that the RCM of large rings is often performed under high dilution ( 0.05-100 mM ) "'( A ) "'to reduce intermolecular reactions; while the RCM of common rings can be performed at greater concentrations, even thermodynamic products by increasing temperature "'( B ) "', to decrease viscosity of the reaction mixture and therefore increase thermal motion, as well as increasing or decreasing reaction time "'( C ) " '.
