Abstract

Abstract Fp (η 2-vinyl ether) BF 4 complexes (2a–d)(Fp= η-C 5 H 5 Fe (CO) 2) are useful starting materials for the preparation of thermodynamically unstable Fp (η 2-acrylonitrile) BF 4 complexes (3a–d). Treatment of 2a–d with tetraethylammonium cyanide at 0 C gave the neutral adducts 4a–d which were transformed, in the presence of fluoroboric acid etherate at− 78 C, to the acrylonitrile complexes 3a–d. These salts are unstable at room ...
