Abstract A series of acyclic silyl diketonates,(CH 3) 3 Si (dik), where dik= dipivaloyl- methanate, diisobutyrylmethanate and hexafluoroacetylacetonate, along with a new series of cyclic acetylacetonates of the type CH 3 (-CH 2 (CH 2) x CH 2-) Si (acac), where x= 1, 2, and 3, have been shown to possess enol ether structures in which the acyl group is positioned cis or trans to the silyl group. The ratios of cis to trans configurations in the (CH ...
