Lewis acid promoted substitution reactions employing Meldrum’s acid and 5-methyl Meldrum’s acid as carbon-based leavinggroups are described which transform unstrained quaternary and tertiary benzylic Csp3–Csp3 bonds into Csp3–X bonds (X = C, H, N). Importantly, this reaction has a broad scope in terms of both suitable substrates and nucleophiles with good to excellent yields obtained (typically >90%)
