The
hydrolisis of coordinated propargyl cations [Cp2W2(CO)4(m-h2,h3-(HCºCCR1R2)]+
Abstract
As
shown by 121Sb Mössbauer measurements, oxidation of Sb(III)
ions located on the surface of Cr2O3 produces an increase
in the value of transferred hyperfine field H(121Sb) of about a
factor of 2. The observed variation is consonant with that previously reported
for 119Sn surface. The reactivity
of carbocations [(m-h2,h3-HCºCCR1R2)Cp2W2(CO)4]+
with primary (R1=R2=H), secondary (R1=H,R2=Me)
and tertiary (R1=R2=Me) coordinated propargyl cations in
the reaction of hydrolisis is increased from primary to tertiary ones.
