Liang, Shuang,Cao, Xiaohui,Yan, Xilong,Chen, Ligong
, p. 555 - 556 (2012)
A mild and practical synthetic route for biphenyls is established. Isopropyl nitrite was prepared from sodium nitrite, isopropanol and hydrochloric acid. The biphenyl compounds were obtained from the diazotisation of aniline derivatives with the generated isopropyl nitrite and the coupling reaction with benzene derivatives in the presence of CuCl as a catalyst in good yields.

Halodeboronation of organotrifluoroborates using tetrabutylammonium tribromide or cesium triiodide
Yao, Min-Liang,Kabalka, George W.,Blevins, David W.,Reddy, Marepally Srinivasa,Yong, Li
experimental part, p. 3738 - 3743 (2012/06/30)
Halodeboronation of organotrifluoroborates using commercially available tetrabutylammonium tribromide (TBATB) or cesium triiodide in aqueous medium is reported. The mild, transition metal-free method has proven to be tolerant of a wide range of functional groups. High regio- and chemoselectivity are observed. Two synthetic routes to (Z)-dibromoalkenes from alkynes, through stereodefined (Z)-2-bromoalkenyltrifluoroborates and (Z)-1,2-bis(boryl) alkenyltrifluoroborates, have been developed using the TBATB mediated bromodeboronation as the key step.
