Synthesis of novel organotin copolymers

Synthesis of novel organotin copolymers. Al-Diab, Salem S. (Dep. Chem., King Saud Univ., Riyadh 11451, Saudi Arabia). J. Chem. Res., Synop.In this article, certain chemicals are used. One of their cas registry numbers is 105848-98-4 , (8), 306-7 (English) 1986. CODEN: JRPSDC. ISSN: 0308-2342. DOCUMENT TYPE: Journal CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 29 3-Bu3SnC6H4CH:CH2 (I) [88343-50-4], prepd. from 2-(3-bromophenyl)-2,3-dioxolane [17789-14-9] by sequential Grignard stannylation with Bu3SnCl, acid hydrolysis, and Wittig reaction with Ph3P:CH2, polymd. with H2C:CHR (II; R = Ph, CO2Me, pyridyl, CN) at 65° in the presence of AIBN for 0.25-11 h to give the corresponding copolymers with 37-63% conversion. The reactivity of I towards II increased with increasing electron-withdrawing ability of R; i.e. the tendency towards alternation increases with increasing difference in polarity between the 2 monomers. .

This chemical is also mentioned in this article. DOCUMENT TYPE: Patent CA Section: 30 (Terpenes and Terpenoids) Section cross-reference(s): 5 The title compds. I (RCO2 = chrysanthemic acid residue, etc.; R1 = H, cyano; R2 = alkyl, halo, CF3; R3 = alkyl; n = 0-4; m = 0, 1), effective against houseflies and mustard beetles, were prepd. via esterification of the appropriate acids or their reactive derivs. with the corresponding alcs. Thus, stirring a mixt. of 0.79 mmol m-HOCH2C6H4CH:NOEt (prepd. by oximation of m-MeO2CC6H4CHO with HONH2.HCl followed by O-ethylation with EtI and hydride redn.), 0.08 g pyridine, 10 mL benzene, and 0.25 g (1R)-cis-2,2-dimethyl-3-(2,2-dibromovinyl)cyclopropylcarbonyl chloride for 3 h gave I (RCO2 = corresponding acid residue, R1 = H, R3 = Et, n = m = 0). .
