Palladium catalysis has enabled the development of modified Wacker protocols. For example, in the presence of a high concentration of bromide anions, the typical Wacker oxidation can be suppressed in favor of a 1,2-dibromination reaction. While 1,2-dibromides are usually obtained conveniently from direct bromination of alkenes, the use of chirally ligated palladium (as in complexes ‌22‌–‌24‌) offers a uniquely efficient way to prepare these compounds ‌25‌ in enantiomerically enriched form (‌Scheme 21‌).[‌83‌]
