1,1,3,3-Tetramethylbutyl isocyanide Chemical Properties, Uses, Production
Chemical Properties
clear colorless liquid
Uses
1,1,3,3-Tetramethylbutyl isocyanide was used in the synthesis of substituted furans and imides.
Application
1,1,3,3-Tetramethylbutyl isocyanide can be added to organometallic reagents to obtain α-metal aldehyde imines, which are used to synthesize useful acyl anion equivalents.
Synthesis
1,1,3,3-Tetramethylbutyl isocyanide is readily available in two steps from 1,1,3,3-tetramethylbutylamine, which is formylated with Formic Acid (86- 90%) followed by dehydration with Dimethylchloromethyleneammonium Chloride (Vilsmeier reagent).
Preparation
To a stirred solution of 83.0 g (0.528 mole) of N-(l,l,3,3-tetramethylbutyl) formamide in 11 of DMF was added dropwise, under a nitrogen atmosphere, a solution made up of thionyl chloride (40.3 ml, 0.55 mole) dissolved in 150 ml of DMF. The addition was at such a rate that the temperature did not exceed -50°C. After the addition, the cooling bath was removed momentarily to allow the temperature to increase to -35°C and then it was replaced while 118.0 g (1.11 mole) of sodium carbonate (anhydrous grade) was added. Then the cooling bath was removed and the reaction mixture was diluted with ice-cold water in a separatory funnel and then extracted with pentane. The pentane extract was dried over sodium sulfate and concentrated, and the product distilled to yield 68.4 g (93% yield), b.p. 55.5-56.6°C (11 mm).
