Blue light promoted room temperature iron-catalyzed C3-alkylation of indenes by alcohols via borrowing hydrogen methodology

Year: 2026

Type: article

Abstract: We reported herein a general iron-catalyzed C3-alkylation of indene derivatives using primary alcohols as electrophilic partners. Noticeably, this transformation was performed with a variety of substituted indenes and alcohols at room temperature thanks to the use of blue light activation. (38 examples, 30–99% yields) Control experiments permitted to propose a catalytic cycle explaining notably the role of the blue light.
