The allyl complex di-&mgr;-chloro-bis

The title compound, di-&mgr;-chloro-bis[(2,3,4-eta)-ethyl 6, 6-dimethyl-5-oxohept-2-enoato]palladium(II), [Pd(2)Cl(2)(C(11)H(17)O(3))(2)], is a binuclear chloro-bridged palladium allyl complex that was obtained serendipitously From the reaction of 6,6-dimethyl-2-hepten-4-ynoate with Na(2)PdCl(4) in water-containing alcohol. The allyl group is substituted with an ester and a tert-butylcarboxy group. The dimeric molecules link via C-H.O contacts into a two-dimensional network parallel to the bc plane.

(-)-(1R,2S,2'R,5R)-2-(1-Hydroxyprop-2-yl)-5-methylcyclohexanol. corrigendum

The crystal structure of the title compound, C(10)H(20)O(2), was published [Korner et al. (2000). Acta Cryst. C56, 74-75] with an erroneous position for an hydroxy H atom. This has now been corrected and leads to a more sensible hydrogen-bonding scheme.

(1R*,11R*)-Bicyclo[9.4.1]hexadecane-12,16-dione.

The title compound, C(16)H(26)O(2), (I), prepared by oxidation of (1R*,11R*)-12-hydroxybicyclo[9.4.1]hexadecan-16-one using pyridinium dichromate, has a trans configuration of the two fused rings and represents an interesting precursor for the synthesis of macrocyclic structures.
