Internal B-O Bond-Facilitated Photoisomerization of Boranes: Ring Expansion Versus Oxyborane Elimination/Intramolecular Diels-Alder Addition

Boron compounds (1-4) containing an internal B-O bond have been found to undergo facile multistructural transformations upon irradiation at 365 or 410 nm, generating rare 8-membered B,O-heterocycles (1c-4c). In addition, 2 and 3 also undergo an intramolecular Diels-Alder addition and oxyborane elimination concomitantly, via intermediates 2b/3b, producing 2d/3d. The pathways to isomer c and product d were found to be a thermal process and a photo process, respectively.

Phosphino[tris(trimethylsilyl)methyl]boranes and 2,4- bis[tris(trimethylsilyl)methyl]-1,3,2,4-diphosphadiboretanes [1]

The reaction of tris(trimethylsilyl)methylboron dihalides (Me 3Si)3CBX2 (X = Cl, F) with the lithium phosphides LiPHtBu and LiPHmes leads to the phosphinoboranes (Me 3Si)3CBX-(PHR), (Me3Si)3CB(PHR) 2 or the 1,3,2,4-diphosphadiboretanes [(Me3Si) 3CB(PR)]2, depending on the ratio of the reagents, the reaction temperature and concentration. High dilution and low temperatures are required for the synthesis of (Me3Si)3CB(Hal)PHR (1-3) in order to prevent the formation of (Me3Si)3CB(PHR) 2 (4 and 5). The latter compounds are best prepared in a two step phosphination from (Me3Si)3CBHal2 and LiPHR. At higher temperatures the four-membered 1,3,2,4-diphosphadiboretanes [(Me 3Si)3CB(PR)]2 6 and 7 are the most stable compounds. On the other hand, compounds of type (Me3Si) 3CB(Hal)PR2, 8 and 9, are thermally more stable than the monophosphinoboranes 1-3. Phosphinoboranes of type (Me3Si) 3CB(PR2)2 (R = tBu, mes) could not be prepared. NMR and mass spectral data are in accord with the monomeric nature of compounds 1 to 9.
