Fig. 3: Evaluation of BCHs as alkyl radical donors and derivatization of alkylation products.
From: Bicyclo[2.2.0]hexene derivatives as a proaromatic platform for group transfer and chemical sensing
a Scope of alkylated BCHs. b–d Scope of radical acceptors. e Derivatization of alkylation products. Standard conditions: 2 (0.20 mmol), 3 (0.40 mmol), 6 (2.5 or 5 mol%), in 2.0 mL DCM at room temperature under blue light irradiation (450 nm) for 12–36 h. Yields refer to isolated yields after chromatography. aDetermined by 1H NMR using an internal standard. bIn the presence of 20 mol% TFA. cCarried out at a 0.10 mmol scale.
