Potassium Chloride Solution

IrCl3(PEt3)3 is readily converted to IrHCl2(CO)(PEt3)2 by treatment with carbon monoxide in hot acetone, ethanol, or 2-methoxyethanol. Perchlorate, tetrafluoroborate, and tetraphenylborate salts containing the [IrCl2(CO)(PEt3)3]+ cation have been prepared, but attempts to obtain salts containing the [IrHCl(CO)(PEt3)3]+ cation give only the neutral hydride, IrHCl2(CO)(PEt3)2. The reactions of [IrCl2(CO)(PEt3)3]+ with ethanol, water, lithium aluminum hydride, aqueous potassium chloride solution, and sodium alkoxides are described.

Work Up

The reduction of ethyl phenylpropiolate by lithium aluminum hydride results in partial reduction of the triple bond to give trans-cinnamyl alcohol. If ethyl phenylpropiolate is reduced by LiAlD4 followed by work-up with acetone and H2O the product is the specifically labeled compound, trans-3-phenyl-2-propen-1-ol-1,1,2-d3. If the ester is reduced with LiAlH4 followed by work-up with acetone-d6 and D2O the product is trans-3-phenyl-2-propen-1-ol-O,3-d2. Oxidation of these two products by sodium ruthenate leads to formation of trans-cinnamic acid-α-d and trans-cinnamic acid-β-d, respectively.
