| Abstract: | Synthesis of fulvenes via 1-chloroaklyl-acetates The synthesis of fulvenes (5) via l-chloroalkyl acetates (3) is extended to 6-alkyl-fulvenes with branched side-chains, to 6-phenylfulvene (5f) and 6-(2-furyl)fulvene (5g) , as well as to 6-vinylfulvenes ( 5h and 5i ) containing chlorine and acetoxy-substituents in ω-position. The reaction is carried out at low temperature under water-free conditions. The purification of the reaction products is simple. - An improved procedure for the preparation of pure fulvene ( 5a , R=R′=H) is reported. |
