# Structure of compound

The synthetic scheme below makes reference to a reagent $\ce{(CH_3)_3COCl}$ that is added at some points in the synthesis.

What kind of structure does $\ce{(CH_3)_3COCl}$ have? The closest structure I can imagine is that of $\ce{(CH_3)_3CCOCl}$ with an extra carbon for the 3 methyl groups to be attached to. $\ce{(CH_3)_3COCl}$ seems to imply that the 3 methyl groups are attached to the carbonyl carbon (which is impossible).

• $\ce{Me3COCl}$ is possible but would require a chlorine-oxygen bond. Seems like a typo to me … – Jan Sep 2 '17 at 4:42
