Yield: 8 %Spectr. , 5 %Spectr.

Reaction Conditions:

with triethylsilane in dichloromethane at 20; for 0.666667 h;

Steps:

Deoxygenation of benzylic alcohols with Sn-Mont / Et3SiH
General procedure: In around-bottomed flask was placed 30 mg of Sn-Mont, 1 mmol of 1a, 2 mmol of Et3SiH and 5 mL of CH2Cl2. The mixturewas stirred at room temperature for 40 min. Then, Sn-Mont was filtered off, andthe filtrate was concentrated and analyzed by NMR using mesitylene as theinternal standard. In order to completely stop the reactions in entries 1 to 5 of Table 2, the reaction mixtures were cooled down in an ice-waterbath for 10 min just after the specified reaction times, and then the clay wasfiltered off.
