A blue light-induced formal insertion reaction of α-siloxy carbene into the C-H bond of 1,3-diketones has been reported. Under the irradiation of blue light, acylsilane converted to α-siloxy carbene, which then undergoes formal C-H bond insertion reaction with the enol form of 1,3-diketone. This method using readily available and relative stable acylsilane as carbene precursor, which features a simple and metal-free approach under mild conditions. Moreover, the synthetic potential of this protocol has been demonstrated by performing the reaction on a gram scale with comparable high yield.

Key words: photoinduced, α-siloxy carbene, 1,3-diketone, C-H bond insertion reaction
