摘要：
(Chemical Equation Presented) Mind your Ps and Bs: Valence isomerizations of PBBP 1,3-butadienes are investigated and compared to those of PCCP and all-carbon systems. The 2,3-diborata-1,4-diphosphoniabuta-1,3-dienes thermally isomerize to bicyclo[1.1.0]butanes or cyclobutane-1,3-diyls. Under photolytic activation, the bicyclo[1.1.0]butanes rearrange into cyclobutenes. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
