Filed:

Jun 15, 2001

Appl. No.:

09/882657

Inventors:

Mark Victor Michael Emonds - Midland MI
Gary A. Roth - Midland MI

Assignee:

Dow AgroSciences LLC - Indianapolis IN

International Classification:

C07D48704

US Classification:

544263

Abstract:

2-Amino-5, 8-dimethoxy[1,2,4]triazolo[1,5-c]-pyrimidine is prepared from a 5-chloro or 5-methoxy substituted 3-amino-8-methoxy[1,2,4]triazolo[4,3-c]-pyrimidine by reaction with methoxide in an alcohol solvent. Both rearrangement and, when the 5-substituent is chloro, methoxy substitution can be accomplished directly.

Assignee:

DOW AGROSCIENCES LLC - Indianapolis IN

International Classification:

C07D 213/32

US Classification:

546339

Abstract:

2-Trifluoromethyl-5-(1-substituted)alkylpyridines are produced efficiently and in high yield from an 4-alkoxy-1,1,1-trifluorobut-3-en-2-one by a condensation and a cyclization reaction. Both reactions are performed in the same nonpolar solvent without isolation and purification of intermediates.

C07C 69/94
C08F 4/16

US Classification:

526213, 502169, 560 86

Abstract:

The present disclosure is directed to the production of substituted phenylene aromatic diesters and 5-tert-butyl-3-methyl-1,2-phenylene dibenzoate (or “BMPD”) in particular. The processes disclosed herein produce a liquid BMPD product. The liquid BMPD product unexpectedly creates production efficiencies by reducing the number of production steps, reducing the amount and/or number of reagents required for BMPD production. The liquid BMPD product may also be utilized in procatalyst production yielding similar production efficiencies. The procatalyst composition is subsequently used for olefin polymerization.
