Dimethyl Sulfoxide → HCID 53804914, compound

Participants

Reaction Steps

A mixture of phenylacetonitrile (47.4 g) and 1,3-diiodo-2,2-dimethylpropane (131.2 g) was added dropwise over 2 hours at 25° C. to a stirred solution of powdered potassium hydroxide (90.7 g) in dry dimethylsulphoxide (600 ml) under a nitrogen atmosphere. The mixture was stirred overnight then poured onto water and extracted with ether (1000 ml). The extracts were decolourised with charcoal, filtered and concentrated in vacuo to yield an orange-brown oil which was distilled under vacuum to give 2,2-dimethyl-1-phenylcyclobutane carbonitrile, (b.p. 101°-106° C./0.6mbar) as a pale yellow oil.
