Ka. Rufanov et al., UNUSUAL REACTIVITY OF TRITYLCYCLOPENTADIENYLMETAL DERIVATIVES - MOLECULAR-STRUCTURE OF PH(3)CC(5)H(4)SNME(3) AND PH(3)CC(5)H(4)TICL(3), Journal of organometallic chemistry, 498(1), 1995, pp. 37-39
The preparative synthetic routes to tritylcyclopentadienyl metal deriv
atives of sodium, tin and titanium have been studied. Molecular struct
ures of Ph(3)CC(5)H(4)SnMe(3) (3) and Ph(3)CC(5)H(4)TiCl(3) (4) have b
een defined. The Cl-Ph agostic interaction in the structure of 4 provi
des an unprecedented low reactivity of 4 to nucleophiles of different
natures.
