    Got stuck on figuring out the mechanism for this one reaction, as attached.

    I got to the part where silicon enolate is formed after deprotonation.
    I know Zn-Cu(what is this) and CH2I2 generates the carbene CH2, though wasn't sure on the mechanism for this generation of carbene.

    After that, I couldn't get the spiro compound as required, that is the main part I struggled on really. Please show me how this could be achieved, or at least tell me what would happen.

    Thanks.

    I assume thats an enone as the starting material and the product is bicyclic?

    Have a look at the Simmons–Smith reaction for the second step after you've formed the TMS enolate
