1,2-Ferrocenediylazaphosphinines 2: A new class of nucleophilic catalysts for ring-opening of epoxides

1,2-Ferrocenediylazaphosphinines (1a-c) have been successfully employed as a new class of nucleophilic catalysts for ring-opening of a range of epoxides, their catalytic efficiency in terms of regioselectivity as well as chemical yield comparing well with the existing catalysts in the literature. In contrast, low enantiomeric excesses have been obtained from the reactions of meso-epoxides catalyzed by (R)-1.

Evidence for molecular complexes in the mechanism of additions of iodine monochloride to alkenes

Immediately upon mixing ICl and 2,3-dimethyl-2-butene in CCl4 at 25 deg C a new absorption band due to an alkene - ICl molecular complex appears at 295 +/- 5 nm and decreases rapidly with time.The rate law under conditions of (alkene)0 >> (ICl)0/dt = kexpt(alkene)(ICl)3/AD(alkene)>3 where KAD is the equilibrium constant for the formation of a 1:1 alkene - ICl molecular complex.The addition of ICl to the Z and E isomers of 2-butene and 1-phenylpropene occurs by anti-stereospecific addition.The negative enthalpy of activation for the addition of ICl to 2,3-dimethyl-2-butene is evidence that one or more complexes are involved on the reaction coordinate prior to the rate-determining step.On the basis of analysis of the enthalpy changes during the reaction, it is proposed that both a 1:1 and a 1:2 alkene - ICl molecular complex is involved in the mechanism prior to the rate-determining step.
