Triethylene glycol dimethyl ether (triglyme) [112-49-2] 1.425. Refluxed with, and distd from sodium hydride or LiAlH4. 

It is quite feasible to run the reaction at a bath temperature of 90-95° by adding all reagents to the flask initially a quantitative evolution of carbon dioxide occurs over a period of about 18 hours. The reaction can also be carried out in refluxing 1,2-dimethoxy-ethane (Arapahoe Chemicals, Inc.) over a period of about 50 hours (yield 40-55%), or in triethylene glycol dimethyl ether (Ansul Chemical Company) at a bath temperature of 160° over a period of 2 hours (yield 64%).

A 1-L, three-neck flask was fitted with dropping funnel, a small spinning-band column and a thermometer. Into it were placed a 40% dispersion of Na in mineral oil (38 g, 0.66 mol) and Irielhylene glycol dimethyl ether (375 mL) (freshly vacuum distilled from Na). The flask was heated in an oil bath to 120 CC and a manostat maintained the pressure at 80 Torr. A dry ice chilled trap was present in the line. Over 30 min, a solution of 2,2,4,4-tetramethyl-J,3-dichlorocyclobutanc (69 32 g, 176 mmol) in triethylene glycol dimethyl ether (50 mL) was added at a rate which maintained the internal temperature at 130-140 C. The reaction was moderately exothermic and the mixture turned bright blue. The product was distilled at...

CsF (152 g) was slurried in purified triethylene glycol dimethyl ether (200 g) in a stirred pressure vessel. To the agitated slurry was added tetrafluoroethene (freed of its terpene stabilizer by passage through silica gel just before entering the reaction vessel) until the pressure recorded was 1.7 bar. The mixture was stirred for 1 h and the stirring continued while HCHO (g) (30 g) was slowly introduced. Subsequently, the mixture was heated slowly to 100 C and maintained at 100 C for ca. 5 h during which time the pressure inside the vessel slowly dropped to ca. 1.4 bar. The contents of the reaction vessel were cooled and H20 (25 mL) was added slowly to the mixture. The hydrolyzed mixture was then heated to distill the product yield ca. 130 g bp 81-83 C.
