Recently, small molecules have been utilized as organocatalysts in the ring-opening reactions of aziridines and epoxides with various nucleophiles
Thus, this study performed a detailed examination of the substitution of CI by the nucleophiles
phenols, arylamines, dithionite, nitrite)  or nucleophiles
3]) were effective nucleophiles
due to their high substitution yields.
C-C Crossing Heleroarenes with Nucleophiles
in Synthesis of
Measures to promote the crosslinking capability of PVC include grafting the PVC chains with polyfunctional nucleophiles
or silanes, the addition of reactive plasticizers into a PVC formulation, and so on.
The phosphorus-chlorine bonds in this polymer are highly reactive to macromolecular substitution by a wide range of nucleophiles
to give a broad spectrum of poly(organophosphazenes).
Measures to promote the crosslinking capability of PVC include the PVC chains with polyfunctional nucleophiles
or silanes, addition of reactive plasticizers Into a PVC formulation, and so on.
The longer-chained 1HPFAs would likely have similarly slow reactivity to 1H-perfluoroethane to form PFCAs or other biological nucleophiles
such as certain amino acids in proteins.
Thus, free sulphhydryls of Cys633 and Cys856 act as nucleophiles
to directly attack electrophiles such as [O.
Among the mechanisms proposed to sesquiterpene lactones action, for example, is the ability of the lactone molecule to react with nucleophiles
present in the DNA molecules or sulfur atoms from amino acids of proteins/enzymes, unleashing an oxidative process (Bachelier et al.
Usually, azocompounds are prepared by diazotization of the aromatic amine in mineral acid at about 0degC followed by coupling with nucleophiles
