Abstract
In the presence of the monothiobinaphthol (MTB) ligand aryl ketones are allylated
by mixtures of Sn(CH2 CH=CH2 )4 /RSn(CH2 CH=CH2 )3 (R = Et, Bu) in high e.e. The presence of water suppresses racemic background allylation.
Key words
tin - asymmetric catalysis - ketones - allylation - thiols

Other Etn Sn(CH2 CH=CH2 )4-n , n = 2-4 species are also present as very minor contaminants in these preparations.
Control reactions using d5 -EtBr confirm that the ethyl group arises from the EtBr used for magnesium activation
in ref. 9. Fresh (silver-coloured) as opposed to aged (>2 years, black-coloured) magnesium
leads only to pure Sn(CH2 CH=CH2 )4 . Electron microscopy in conjunction with EDS studies reveal that the surface of aged
magnesium has an appreciable oxygen content (presumably MgO) and it appears to be
this that favours production of EtMgBr over CH2 =CHCH2 MgCl.

Experimental Procedure: All operations were performed under argon; toluene was distilled
from sodium. A toluene solution of MTB 2 (24 mg, 0.08 mmol in 1.0 mL) was treated with a mixture of Sn(CH2 CH=CH2 )4 /SnR(CH2 CH=CH2 )3 (0.7:0.3 mol fraction mix, 0.46 mmol total Sn content, R = Et, Bu). For the ‘dry’
catalyst this mixture (R = Et) was heated directly for 2 h at 52 °C. For the ‘wet’
catalyst water (3 µL, 0.16 mmol) was added to the mixture (R = Bu) prior to the heating
period. The mixtures were cooled to ambient temperature, the ketone 1 (or 4 ) (0.4 mmol) added and the mixture stirred whilst its composition was monitored by
GC, HPLC, or 1 H/119 Sn NMR spectroscopy. Flash chromatography afforded the known alcohols 3 (or 5 ) as essentially single products. Enantioselectivities were determined by GC (CYCLODEX-B
for 3c , oktakis (6-O -methyl-2,3-di-O -pentyl)-γ-cyclodextrin for 3a , 3b , 3e , 3f , 5 ) or HPLC (Chiralcel AD for 3d , Chiralcel OD for 3g ).

<A NAME="RD22301ST-16">16 </A> We speculate that water co-ordination to mixed allyl-alkoxide species may limit
their Lewis acidity preventing them acting as allylation promoters. For a review of
