摘要：

The transfer hydrogenation reactions of various ketones/aldehydes and one-pot cross-metathesis/transfer hydrogenation (CM/TH) reactions of 10-tmdecenal were carried out in water media using first generation ruthenium-indenylidene complex (M1). A stable emulsion with an average particle size of 23.00 ( +/- 7.20) nm was formed in water media using non-ionic (Tween 20) and cationic (dodecyltrimethylammonium chloride) surfactants in the presence of acetophenone, M1 (1%) and sodium formate, yielding corresponding alcohol derivatives in quantitative yields. The performance of M1 (5%) was tested on sequential cross-metathesis/transfer hydrogenation reaction of 10-undecenal using methyl acrylate as the cross-metathesis partner in water. The sequential CM/TH reaction of 10-undecenal was found to proceed even in tap water under air atmosphere using micellar catalyst system, giving the corresponding CM/TH product in 65% yield.
