Preparation of Benzylstannanes by Zinc-Mediated Coupling of Benzyl Bromides with Organotin Derivatives. Physicochemical Characterization and Crystal Structures
No full textBenzyltrialkyl- (1−13) and
benzyltriphenylstannanes (16−22) have been
easily prepared
in a one-pot synthesis via coupling reaction of benzyl
bromide derivatives
(C6H5CH2Br
and
XYC6H3CH2Br, X = H, Y
= o-, m-, p-CH3,
o-, m-, p-F, o-,
m-Cl, and p-Br; X = o-F, Y =
p-Br)
with R3SnCl compounds (R = Et, Pr, Bu, and Ph) in
THF/H2O (NH4Cl) medium
mediated
by zinc powder. Such coupling also occurs with
(Bu3Sn)2O. Dibenzyldibutylstannane
(15)
is prepared by reaction of benzyl bromide with
Bu2SnCl2 or
(Bu2SnCl)2O, and (2-naphthylmethyl)tributylstannane (14) by reaction of
2-(bromomethyl)naphthalene with Bu3SnCl.
13C-
and 119Sn-NMR data are reported for all compounds, and
Mössbauer data for benzyltributylstannanes 10 and 11 and
benzyltriphenylstannanes 16−18 and
20−22. The crystal
structures of Ph3SnBn, with Bn = o-
(17) and
m-ClC6H4CH2
(18) and o- (20) and
m-FC6H4CH2 (21) have been determined
