Abstract

''Time of reaction of 24 h. d 10% SmI2 (THF) 2 are used. 5 10% Aldol is obtained in the crude mixture (measured by GC and NMR).'5% Aldol is obtained in the crude mixture (measured by GC and NMR). E Isomer ratios are measured by NMR. h Time of reaction of five days, yield in crude product. reaction is faster with samarium diiodide, samariu1ntriio-didc and lanthanum triiodide than with the other catalysts. The nature of the metal and of the ...
