α-Hypervalent iodo functionalized phosphonium and arsonium ylides 2 can be used as umpolung ylides to react with nucleophiles to give α-heteroatom substituted ylides 4 in good yields. A tandem sequence of nucleophilic substitution then Wittig reaction occ
α-hypervalent iodine functionalized phosphonium and arsonium ylides and their tandem reaction as umpolung reagents

α-Hypervalent iodine functionalized phosphonium and arsonium ylides 2 can be used as umpolung ylides to react with nucleophiles to give α-heteroatom substituted ylides 4 in good yields. The nucleophilic substitution - Wittig tandem reaction of 2 can occur smoothly to provide an efficient method for the synthesis of (Z)-α-halo-α,β-unsaturated enoates or enones 6, stereoselectively.
