|Synthesis of Crown Ether
Metal Complexes that contain them.
Our attention is centered on the synthesis of crown
ether-containing transition metal complexes in which catalytic activity and/or
product selectivity is "switched" on or off through binding of simple cations by
crown ether units. One project addresses our hypothesis that the
migratory insertion reaction depicted in Scheme 1 for a transition metal
carbonyl complex can be accelerated by the addition of added cation when R is a
A synthetic route has been devised and a model complex has been prepared
We are now preparing a series of complexes where x = 3, 4, 5, and 6. When these compexes are in hand the migratory insertion will be investigated both in the presence and absence of added cation.
