Yield:122-84-9 85 %Spectr.

Reaction Conditions:

with [Ru(2,6-Cl2tpp)Cl2];2,6-dichloropyridine N-oxide in chloroform-d1 at 60; for 2 h;Wacker Oxidation;

Steps:



Alkene substrate (0.1 mmol) and internal standard compound trimethylphenylsilicane(5 μL) were dissolved in CDCl3 (0.5 ml) in an NMR tube to record a 1H NMR. Then[RuIV(TDCPP)Cl2] (2.0 mol%) and Cl2pyNO (1.03 equiv) were added and kept themixture at 60 oC. The progress of the reaction was monitored by 1H NMR. Afterdetermination of the product yield by 1H NMR spectroscopy, the product ketone wasseparated by flash chromatography on silica gel.
