Dative interaction
WebThe most common types of π-interactions involve: Metal–π interactions: involves interaction of a metal and the face of a π system, the metal can be a cation (known as cation–π interactions) or neutral. Polar–π interactions: involves interaction of a polar molecule and quadrupole moment a π system.

WebNov 9, 2024 · The following interaction types were shown to be possible: (A) dative bonding between boronic acids, (B) free boronic acid, and (C) hydrogen-bonded boronic acids. These four-coordinates are also possible: (D) dative bonding between a boronic acids and (E) dative bonding between a boronic acid and oxygen on the PDMS backbone. WebThis paper reports the findings of two experiments that examined the occurrence of syntactic priming—a speaker's tendency to produce a previously spoken or heard structure—during interaction between L2 English speakers. Both studies used confederate scripting to elicit dative constructions from advanced English L2 speakers.
