Conclusions
-
1.
The reactions of 2-thiocyanatoethoxytrimethylsilane with the acid chlorides of halocarboxylic acids and tetracoordinated phosphorus acids proceed according to equilibrium reactions, with the formation of the 2-thiocyanato esters of the corresponding acids.
-
2.
The equilibrium of the reaction is shifted to the right more strongly the more polar and polarizable the bond between the chlorine atom and the carbonyl carbon in the case of the halocarboxylic acids, and the greater the ability of the phosphorus atoms to form an additional bond via the d-orbitals.
