Reinvestigation of the hydrolysis of spiropentyl chloride has confirmed that the product is primarily 2-(hydroxymethyl)-1, 3-butadiene, but with some P-cyclopropylideneethanol formed as well. To test the possibility that these products differ from those of diazotization of spiropentylamine (2-and 3-methylenecyclobutanol) because of a sim-ple leaving-group effect, spiropentanol and some sulfonate esters of it were synthesized. The p- ...
