(Z)-1-Aryl-1-haloalkenes as Intermediates in the Vilsmeier Haloformylation of Aryl Ketones
摘要:
Vilsmeier reagents give (Z)-1-aryl-1-haloalkenes from aryl ketones bearing an electron-donating substituent at the ortho- or para-position. These haloalkenes are intermediates in the Vilsmeier haloformylation of the aryl ketones. Another reaction mechanistic pathway is thus available in certain Vilsmeier haloformylations, in competition with the commonly accepted route by way of an enaminoketone.

present a simple and straightforward protocol for hydrochlorination of terminal arylalkynes to vinyl chlorides using hydrogenchloride under mild reaction conditions. This protocol does not involve any metal catalysts or additives. It is simple, inexpensive, and easy to prepare, and exhibits good reaction activity. The hydrochlorination proceeds smoothly to yield unique regioselective products via the
