1957-FLUOROALKYLMAGNESIUM CHLORIDES 161°. A mixture melting point "with an authentic specimen was not depressed.For a duplicate reaction 3.73 g. (88%) of triphenyl-2furyltin was recovered, melting at 159-160°.

the appropriate chlorinated phenol (0.2 mole) was refluxed for 8 hr. The reaction mixture was then cooled to 25°and slowly reheated to reflux under reduced pressure (10-15 mm.) for 4 hr. to remove the last traces of hydrogen chloride and thus complete the reaction. The product was purified by distillation at reduced pressure through a short Claisen column.Addition of about 0.1 g. of anhydrous magnesium chloride catalyzed the reaction of the chlorinated phenols and facilitated the removal of the hydrogen chloride.
