Behavior of 1,3-di(tert-butyl)-2,4-bis(tetramethylpiperidino)-1,3,2,4-diphospha-dibor etane towards boron halides and adduct formation of a bicyclo[1.1.0]diphosphadiboretane with tris(pentafluorophenyl)borane. Knabel, Klaus; Noeth, Heinrich; Paine, Robert T. (Department of Chemistry, University of Munich, Munich D-81377, Germany). Zeitschrift fuer Naturforschung, B: Chemical Sciences, 61(3), 265-274 (English) 2006 Verlag der Zeitschrift fuer Naturforschung. CODEN: ZNBSEN. ISSN: 0932-0776. DOCUMENT TYPE: Journal CA Section: 29 (Organometallic and Organometalloidal Compounds) Section cross-reference(s): 75 While the diphosphadiboretane (t-BuP:Btmp)2 (1; tmp = 2,2,6,6-tetramethylpiperidino) reacts with BX3 (X = Cl, Br, iodo) by BN cleavage producing a no. of unidentifiable products, a new tricyclic BP ring system 2 (shown as I), contg. B3P3, PB2C2 and C6 rings, results from the combination of PhBCl2 and 1. B-Chlorocatecholborane and 1 give access to the diborylphosphine tmpBCl-PtBu-cat (3; Hcat = pyrocatechol). The selectivity of the reactions increases as the Lewis acidity of B halide decreases. The structures of compds. 2 and 3 were detd. by x-ray structure anal. The bicyclic (tmpBP)2 4 forms no adducts with MeI, CF3SO2Me or Ph3C(SnCl5). However, it adds B(C6F5)3 to give 10 (shown as II; R = C6F5), the 1st BX3 adduct of this bicycle that is fully characterized including its mol. structure. .
