Synthesis of the first stable metadithiophosphonate

Synthesis of the first stable metadithiophosphonate. Navech, J.; Majoral, J. P.; Kraemer, R. (Univ. Paul Sabatier, Toulouse 31062, Fr.). Tetrahedron Lett., 24(52), 5885-6 (English) 1983. CODEN: TELEAY. 18871-66-4 and 89218-32-6 are also in the experiment. ISSN: 0040-4039. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) RPR1R2 [R = 2,4,6-(Me3C)3C6H2; R1 = R2 = H; R1R2 = CHNMe2, CMeNMe2] reacted with S to give metadithiophosphonate RP(S)(S), which gave RP(S)(SH)OMe on treatment with MeOH. RP(S)(S) (same R) underwent cycloaddn. with H2C:CMeCMe:CH2 to give phosphathiacyclohexene I. .

Herbicidal use of .beta.-aminoatroponitriles. Beck, James Richard (Lilly, Eli, and Co., USA). U.S. US 4012224 15 Mar 1977, 6 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: A01N009-20. NCL: 071105000.Several substances with their cas registry numbers 18871-66-4 and 62739-02-0 may be metioned in this study. APPLICATION: US 75-636884 2 Dec 1975. DOCUMENT TYPE: Patent CA Section: 25 (Noncondensed Aromatic Compounds) Section cross-reference(s): 5 .beta.-Aminoatroponitriles m-RC6H4C(CN):CR1NR2R3 (I; R = H, halo, CF3; R1, R2, R3 = H, Me, Et) were prepd. (2 methods) and tested as herbicides at an application rate of 1.0-20 kg/ha. Thus, PhCH2CN with Me2NCH(OEt)2 gave I (R = R1 = H; R2 = R3 = Me). Treatment of m-F3CC6H4CH2CN with Me formate in the presence of NaOMe gave m-F3CC6H4C(CN):CHOH, which underwent O-methylation with MeI and the ammonolysis to give I (R = CF3, R1 = R2 = R3 = H). .
