摘要

In summary. this work provides easy access to 1-. 2-. 3-, and 4-nitrofluorenones 8a—d (31— > 46%) and-fluorenes 10a—d in (12—> 67%) overall yields. Although the route to 10d is some-what inefficient, all nitrofluorenone and-fluorene products are obtained as single isomers. whose ultrapurification is not frought with the difficulties of separation of trace quantities of contaminating isomers.
