The synthesis of unsymmetrical biaryls with a methylthio group is achieved using the air-stable palladium-phosphinous acid complexes, [(t-Bu)2P(OH)]2 PdCl2 (POPd), as the catalyst. A great variety of substituted bromobenzenes having electron-withdrawing and electron-donating functional groups in para and meta positions have been successfully coupled with 3-methylthiophenylboronic acid.

The synthesis and application of fluorous boronates without perfluorinated solvents
Wang, Chun-Yan,Meng, Wei-Dong,Huang, Yan-Gen,Qing, Feng-Ling
, p. 996 - 1001 (2007/10/03)
The synthesis of a fluorous diol 4 bearing a perfluorodecyl chain was described. A series of boronic acid were attached to 4 by esterification. The purification of the products was fulfilled by facile filtration instead of expensive and environmental troublesome fluorous liquid-liquid extraction. The Suzuki cross-coupling reactions of the formed fluorous boronates 5 underwent smoothly and the fluorous diol 4 was recycled in good yields.
CATIONIC BENZOANNELATION OF ACTIVE METHYLENE KETONES VIA OXOKETENDITHIOACETALS
Singh, Gurdeep,Ila, Hiriyakkanavar,Junjappa, Hiriyakkanavar

α-Oxoketendithioacetals are shown to be useful intermediates for benzoannelation of α-methylene ketones by reactions with allylmagnesium bromide followed by cationic cyclisations of the resulting carbinolacetals.
