Dichlorocarbene reacts with alkenes in a formal [1+2]cycloaddition to form geminal dichlorocyclopropanes. These can be reduced to cyclopropanes or hydrolysed to give cyclopropanones by a geminal halide hydrolysis. Dichlorocyclopropanes may also be converted to allenes in the Skattebøl rearrangement. In the Reimer–Tiemann reaction dichlorocarbene reacts with phenols to give the WebThe melting point of polypropylene is 160°C / 320°F) Low temperature threshold: polypropylene becomes brittle below 0°C.
