Isoamyl Formate, 512,

Formate esters generally become less toxic as the alcohol moiety increases up to C. With this increase in alkyl si2e, the LD q (oral, rabbit) increases from 1.62 g/kg for methyl formate to 3.0 g/kg for isoamyl formate [110-45-2]. In comparison, both aHyl and vinyl formates are more toxic than their saturated analogues. 

Pyrrolealdehyde has been prepared from pyrrole, chloroform, and potassium hydroxide from pyrrolemagnesium iodide and ethyl, propyl, or isoamyl formate and, by the method here described, from pyrrole, phosphorus oxychloride, and dimethylformamide. Smith has suggested a possible intermediate in this process. The method has also been applied to substituted pyrroles and is similar to that described in this series for the preparation of -dimethylaminobenzaldehyde from di-methylaniline. ...
