Hi, everyone. I have just registered a new account and I want to post 2 questions about nitrene reactions but I don't know how to post images. Could anyone teach me how to post images? Thank you very much in advance.

Hi 190303458, under the window where you type your message, click on "additional options", and from the "Attach" area you can designate a file from your computer.

It would also be possible to store an image somewhere on the Web and link to it in your message, but mind the accessibility restrictions, the volatility of other websites, and so on.

For the following 2 questions about nitrene reactions, are the corresponding products I proposed correct?

Hi Enthalpy, thank you very much for your instructions.

It's been a while since I looked at nitrenes but consider if C(aryl)-H bonds are the most likely to break for part 1. Not really sure for part 2 - certainly the product you have drawn seems feasible but I think you may get a mixture of products.

For question 1, after forming a nitrene by expelling nitrogen, the nitrene can undergo Wolff rearrangement to form a isocyanate. I'm not sure whether this isocyanate will undergo [4+2] cycloaddition with toluene or not. For question 2, I think it should be insertion to C-H bond by nitrene.
