Visible-light-induced reusable decatungstate-photocatalyzed radical cascade alkylation/cyclization of isocyanides with simple alkanes, ethers and ketones

With reusable sodium decatungstate (NaDT) as the photocatalyst, hydrocarbons (alkanes, ethers and ketones) as the alkylating agents, a wide range of alkylated fused N-heterocycles were obtained in high yield.
