For some time, our group has been studying the low-temperature spectroscopy and photochemistry of 5-membered ring heteroaryl carbenes. These highly reactive molecules have been shown to undergo complex rearrangements. Some of the photoproducts of these carbenes include highly strained 6-membered ring cumulenes, which are very rare and poorly understood. We will describe experiments on the first benzothiazolyl(trifluoromethyl)carbene using low-temperature matrix isolation techniques. Besides the carbene, we will also present spectroscopic evidence for the corresponding 6-membered ring ketenimine photoproduct.
