Abstract

The reaction of arene ruthenium (II) complexes [Ru (η6-C6Me4R2)(PMe3) Cl2](1, R= Me; 1′, R= H) with propargyl alcohol derivatives HC C (H)(OH)(p-C6H4 X)(a, X= HC C (H)(OH); c, X= CHO; d, X= CH CH2; e, X= CH CH CH CH2) and methanol gives the (methoxy)-alkenylcarbene ruthenium complexes [Ru (η6-C6Me4R2)(PMe3)(Cl)( C (OMe)(CH CH-p-C6H4 X)][PF6](2a) and (2′ c–e). Similarly, the half-sandwich ...
