资源简介:
A carbene-stabilized dithiolene zwitterion (3) activates ammonia, affording 4• and 5, through both single-electron transfer (SET) and hydrogen atom transfer (HAT). Reaction products were characterized spectroscopically and by single-crystal X-ray diffraction. The mechanism of the formation of 4• and 5 was probed by experimental and computational methods. This discovery is the first example of metal-free ammonia activation via HAT.
