Thiostannylation of arynes with stannyl sulfides: synthesis and reaction of 2-(arylthio)arylstannanesElectronic supplementary information (ESI) available: experimental section. See http://www.rsc.org/suppdata/cc/b4/b405883f/
Arynes were found to insert into a sulfur-tin sigma-bond of stannyl sulfides to give a variety of 2-(arylthio)arylstannanes, whose carbon-tin bonds were applicable to further transformations.

The palladium-catalyzed cross-coupling reaction of 9-organothio-9-borabicyclo[3.3.1]nonanes with organic electrophiles: Synthesis of unsymmetrical sulfides
palladium-catalyzed cross-couplingreaction of 9-organothio-9-borabicyclo[3.3.1]nonane (9-RS-9-BBN) with organicelectrophiles, such as iodoarenes, l-iodo-l-alkenes, allyl carbonate and propargyl carbonate. Iodoarenes and l-iodo-l-alkenes were smoothly converted into the corresponding sulfides at 50°C in the presence of PdCl2((dppf) 3 mol%) and K3PO4 (3 equiv.) in DMF. In contrast, the cross-couplingreaction of 9-RS-9-BBN
不对称硫化物的合成通过钯催化9-有机硫-9-硼环[3.3.1]壬烷(9-RS-9-BBN)与有机亲电子试剂(如碘代芳烃)的交叉偶联反应而高收率地进行,1-碘-1-烯烃,碳酸烯丙酯和碳酸炔丙酯。在存在于DMF中的PdCl 2((dppf)3 mol%)和K 3 PO 4(3当量)的情况下,在50℃下将碘代芳烃和1-碘-1-烯烃平稳地转化为相应的硫化物。相反,在DMF中9-RS-9-BBN与烯丙基或炔丙基碳酸酯的交叉偶联反应在没有碱的帮助下发生。Pd(dba)2催化的两个反应-dppf区域选择性地产生烯丙基和烯丙基硫化物,产率极高。讨论了反应的范围和局限性,以及改变反应条件的影响。

kinetic study has been conducted on the reaction of (arylthio)trimethylstannanes with 1-aryl-1-bromoethanes. The reaction of the arylbromoethane bearing an electron-donating substituent was found involving unimolecular ionization of the arylbromoethane. The other reactions, however, were found to be second-order reactions. The nature of the second-order reactions was shifted from one involving unimolecular
