Stereochemistry of hydrogenation of cyclonona-1,2-diene with supported platinum metals and soluble rhodium complexes as evidence for allylic intermediates
Abstract
The formation of trans-cyclononene upon hydrogenating cyclonona-1,2-diene with supported platinum metals or the soluble complexes ClRh(PPh3)3 and HRh(PPh3)4 as catalysts furnishes evidence that π-allylic structures are intermediates in these reactions.
