| Abstract: | We herein report a base-promoted generation of sterically hindered 1,3,5-triaryl 2-pyridylidene from the corresponding pyridinium salt. The thus-generated 2-pyridylidene was trapped by S(8) and Me(2)SAuCl to form 2-pyridinethione and a 2-pyridylidene-gold(I) complex, respectively. Rearrangement of pyridylidene to pyrido1,2-a]indole indicates high reactivity of the carbene center of 2-pyridylidene. |
