| Abstract | Cyclopropylacetylene reacts with two molar equivalents of Piers' borane [HB(C6F5)2] under mild conditions by an addition/rearrangement sequence with cyclopropyl ring opening to give a mixture of two a-B(C6F5)2 substituted tetrahydroboroles. This compound forms an active frustrated Lewis pair with PBu3 that heterolytically splits dihydrogen and adds carbon dioxide as a geminal chelate bis-boryl component. The respective reactions of the two-fold HB(C6F5)2 addition to Ph-CH2CH2C^CH were studied as a geminal Lewis acid reference. Most of the products were characterized by X-ray diffraction. |
