Stabilization of thiazinetetrahydronitromethylene (TTNM)

Stabilization of thiazinetetrahydronitromethylene (TTNM). (Hokko Chemical Industry Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59130804 A2 27 Jul 1984 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: A01N043-86; A01N025-22. APPLICATION: JP 83-5248 18 Jan 1983. DOCUMENT TYPE: Patent CA Section: 5 (Agrochemical Bioregulators) Triarylphosphines markedly improve stability of TTNM [58842-20-9]. Thus, a powder compn. contg. 2% TTNM and 1% tricyclohexylphosphine [2622-14-2] was 96.5% stable at 40° for 30 days, as compared to 5.9% without the phosphine.

Kokai Tokkyo Koho JP 2007023252 A 1 Feb 2007, 18pp. (Japanese).Some commonly used reagents like 2622-14-2 and 921770-35-6 are used in this experiment. (Japan). CODEN: JKXXAF. APPLICATION: JP 2005-328448 14 Nov 2005. PRIORITY: JP 2005-177621 17 Jun 2005. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Title method involves polymg. 32 B-bearing arom. monomers with 32 reactive functional group-bearing arom. monomers, or polymg. B- and reactive functional group-bearing arom. monomers in org. solvents with catalytic Pd complexes, alkylphosphine ligands, and compds. chosen from alkali metal hydroxides and alkoxides, and alk. earth metal hydroxides and alkoxides. Thus, 2,2'-(9,9-dioctyl-9H-fluorene-2,7-diyl)bis(1,3,2-dioxaborolane) was polymd. with 2,7-dibromo-9,9-didodecyl-9H-fluorene in toluene and DMSO in the presence of tris(dibenzylideneacetone)dipalladium(0), tricyclohexylphosphine, and LiOMe at 100° for 8 h to give a polymer with Mw 320,000 and Mn 210,000. .
