Cyclopropanecarbonyl chloride

Cleavage of the C-Cl bond in a cyclopropanecarbonyl chloride occurs to give the corresponding cyclopropanecarbaldehyde the reagent used was lithium tri-ferf-butoxyaluminum hydride in an ethereal solvent.The yields were rather low. 

Cyclopropanecarbonyl chlorides were converted to 5-ter/-butyl carbothioates in good yield on reaction with tert-butyl thiol in the presence of pyridine. ... 

Cyclopropanecarbonyl chlorides are capable of forming cyclopropyl ketones under the correct reaction conditions. In the presence of a Lewis acid, alkenes and aryl... 

Treatment of cyclopropanecarbonyl chloride with excess of lithium tetrakis(trimethyl-silyl)aluminate in the presence of a catalytic amount of copper(I) cyanide gave cyclopropyl-carbonyltrimethylsilane in 89% yield. 

Treatment of cyclopropanecarbonyl chloride with a variety of 4-acyl-l,3-dihydroxybenzenes in the presence of potassium carbonate under homogeneous and phase-transfer conditions afforded 2-cyclopropyl-7-hydroxychromones. The yields were significantly higher (15-20%) under the latter reaction conditions. ...

The synthesis of buprenorphine has a certain similarity to that of etorphine. After the Diels-Alder reaction of thebaine with methyl vinyl ketone, the double bond is hydrogenated. Then follows a Grignard reaction with t-butyhnagnesium chloride. For modification of the tertiary amine, this is demethylated with cyanogen bromide (von Braun reaction) and treated with cyclopropanecarbonyl chloride. Following reduction with lithium aluminium hydride, the aromatic methoxy-group is finally replaced by nucleophihc substitution under forcing conditions.
