Assignee:

Minnesota Mining and Manufacturing Company - St. Paul MN

International Classification:

A01N 4106

US Classification:

71103

US Patent:

39377385, Feb 10, 1976

Filed:

Apr 25, 1974

Appl. No.:

5/464492

Inventors:

James R. Throckmorton - Woodbury MN

Assignee:

Minnesota Mining and Manufacturing Company - St. Paul MN

International Classification:

C07C 4916
C07C 4714

US Classification:

260593H

Abstract:

Perhaloalkanesulfenyl chlorides are reacted with aldehydes and ketones to provide novel (perhaloalkyl)thio-substituted aldehydes and ketones which are useful organic solvents and intermediates. As intermediates, these compounds are especially useful in the preparation of their carbamate derivatives which have pesticical utility.

Filed:

Apr 26, 1974

Appl. No.:

5/464493

Inventors:

James R. Throckmorton - Woodbury MN

Assignee:

Minnesota Mining and Manufacturing Company - St. Paul MN

International Classification:

C07C13100

US Classification:

260566AC

Abstract:

The compounds 1-trifluoromethylthio-3,3-dimethyl-2, butanone-O-methylcarbamoyloxime and 1-difluoromethylthio-3,3-dimethyl-2-butanone-O-methylcarbamoyloxime are prepared from certain novel ketone and oxime intermediates. These compounds have insecticidal activity and are particularly effective against the Western and Northern corn rootworms, Diabrotica virgifera and Diabrotica longicornis respectively.

US Patent:

43318177, May 25, 1982

Filed:

Jan 16, 1981

Appl. No.:

6/225739

Inventors:

James R. Throckmorton - Woodbury MN

Assignee:

Minnesota Mining and Manufacturing Co. - Saint Paul MN

International Classification:

C07C 8500
C07C 8524

US Classification:

564430

Abstract:

A process for the preparation of a 4-arylthioaniline from the corresponding 4-unsubstituted aniline which comprises reacting the latter with an alkali metal thiocyanate in the presence of halogen to provide the 4-thiocyanoaniline, reacting it with an alkali metal sulfide to convert the thiocyano moiety to an alkali metal mercaptide group followed by heating with cuprous oxide then with an aryl halide to form the desired product.
