Abstract

The Arrhénius parameters of solvolysis reactions and Sn2 exchange of trans cinnamyl-and β-phenylpropargyl chlorides have been measured.
An approximately equal transmission of polar effects through the C-C double and triple bonds has been observed when the mechanism is Sn2.
On the contrary, for an SN1 mechanism, this transmission is much more important for a C-C double bond than for a triple bond.
