Abstract
The Ag+ induced aromatic substitution reactions of 3-( 1 -bromomethyl)-5,6-dihydro-l,4,2-dioxazine derivatives via an a-acyl cation equivalent are described. ... Nitrones and oxime ethers have been shown to have dual properties in supporting negative or positive charge at the position next to the C=N group. Such compounds can be efficiently metallated on the a-carbon atom to form reagents (a-acyl anion equivalents) that are useful synthetic inter- mediates in ...
