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.
