STEREOSPECIFIC INCORPORATION OF CO-13 INTO OLEFINIC SUBSTITUTED METAL-CARBONYL COMPOUNDS
Additional Document Info
The triene complex, (bicyclo[6.1.0] nona-2,4,6-triene)molybdenum tricarbonyl, has been observed to react with 13CO in solution to afford stereospecifically the axially labelled 13CO tetracarbonyl derivative. Further reactions of this 13CO derivative with triphenylphosphine or bis(1,2-diphenylphosphino)ethane resulted in formation of the cis disubstituted phosphine derivatives with retention of the 13CO label. 1976.
