Applications

Reagent used for Suzuki-Miyaura cross-coupling, stereoselective synthesis via Palladium-catalyzed carboamination, Alkyl-connected 2-amino-6-vinylpurine (AVP) cross linking agent to cytosine base in RNA, Kaiser oxime resin-derived palladacycle as a recoverable polymeric precatalyst in Suzuki-Miyaura cross-coupling reactions in aqueous media and Kinetic resolution of phosphoryl and sulfonyl esters of binaphthol derivatives via Pd-catalyzed alcoholysis of their vinyl ethers.

Notes

Moisture Sensitive, store away from water/moisture. Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store under dry inert gas.

Stable equivalent of the readily-polymerizable vinylboronic acid, first reported by Matteson: J. Org. Chem., 27, 3712 (1962), and more recently adopted by O'Shea as a vinylboron unit for Suzuki cross-coupling reactions with aryl halides to give substituted styrenes: J. Org. Chem., 67, 4968 (2002). The reaction has been applied to the formation of ortho-Boc-amino styrenes, further reaction of which has been developed as a route to diversely functionalized indoles: J. Am. Chem. Soc., 125, 4054 (2003). Copper(II) acetate mediated coupling with phenols affords an efficient synthesis of aryl vinyl ethers: J. Org. Chem., 69, 5087 (2004).
