Title: Photosolvolysis of 2‐Allylated Anilines to 2‐Indanols
Abstract:Abstract It is shown that 2‐allylated anilines ( cf. Schemes 2–4, 7 , and 8 ) on irradiation in protic solvents such as H 2 O.

Schemes 2–4, 7 , and 8 ) on irradiation in protic solvents such as H 2 O. MeOH, and EtOH in the presence of H 2 SO 4 undergo a novel photosolvolysis reaction to yield specifically trans ‐2‐hydroxy‐ and trans ‐2‐alkoxy‐1‐methylindanes. Intermediates are presumably tricyclo[4.3.0.0 1,8 ]nona‐2,4‐dienes formed in an intramolecular [2 s + 2 s ] cycloaddition reaction ( cf. Scheme 7 ). On the other hand, N , N , N ‐trimethyl‐2‐(1′‐methylallyl)anilinium salts 18 ( Scheme 6 ) and 2‐(3′‐butenyl)‐ N , N ‐dimethylaniline ( 17 ) lose on irradiation in MeOH or H 2 SO 4 /MeOH the ammonium group reductively to yield (1‐methylallyl)benzene ( 19 ) and 1‐methylindane ( 20 ), respectively.Read More
