摘要: Abstract The interaction between glycine and F2CO/F2SiO occurs through the formation of a π-tetrel bond C/Si atom carboxyl O atom. energy is some 20 kJ/mol for C⋯O tetrel bond, but exceeds 300 kJ/mol Si⋯O. As part latter complexation process, proton engaged in intramolecular OH··N H-bond transferred across to N, forming zwitterion. This Si⋯O more effective inducing this transfer than placement an aqueous medium, with anionic BH4−, or adding electron glycine.
