The system was exposed to argon several times.  A syringe was then used to draw up 0.39 mL (427 mg, 1.44 mmol, 1.2 equiv) of Bu3SnH and was then dropped slowly into the flask.  A condenser was attached then clamped to the flask and water tubes were attached to the nozzles.  An argon balloon was used as well to protect the top of the condenser.  The system was then placed slowly into an oil bath at 95 C.  The solution was refluxed for 1 hour.  A TLC plate was run to ensure purity.

Syringe– small device, used to transfer small amounts of liquids or gases.  A needle is sometimes attached to the end.


Bu3SnH – Oxytin hydride that is relatively useful for radical reactions because of the weak bond between tin and hydrogen that can be homolytically cleaved.


Argon balloon – An argon balloon is a device filled with argon that helps to maintain a temporary inert pressure in the system.


TLC plate- Silicon Plate used to find the relative polarity of products in different solvents.  This is done by placing a small drop of the product at the bottom of the plate and placing it in a jar of solvent.  The solvent will travel up the plate.  Products of different polarities will travel different distances up the plate. 


Condenser– a piece of laboratory glassware used to cool hot vapors or liquids.  It has a tube running through its center where the hot fluids go and usually water running on the outside to cool the inner tube.
