Diisopropylcarbodiimide → HCID 86738148, compound

Participants

Reaction Steps

A mixture of N,N'-diisopropylcarbodiimide (12.6 g, 0.1 mole), oleyl alcohol (26.8 g, 0.1 mole) and cuprous chloride (60 mg) is stirred at room temperature for 4 hours. Infrared analysis shows the reaction to be virtually complete. The reaction mixture is placed on a column of alumina (454 g) and eluted with methylene chloride to give 36.2 g of O-oleyl-N,N'-diisopropylisourea. The product is identified by mass spectrometry (molecular ion at m/e 394), infrared spectroscopy (the C=N band at 1660 cm-1) and nuclear magnetic resonance in deuterated chloroform; resonances are given in δ relative to tetramethylsilane: 0.9-2.2 (multiplet 37 protons); 2.9-3.8 (multiplet 3 protons); 4.0 (triplet, 2 protons) 5.3 (multiplet, 2 protons).
