Germaacid chloride, germaester, and N-germaacyl pyrrole compounds were not known previously. Therefore, donor-acceptor-stabilised germaacid chloride (i-Bu)2ATIGe(O)(Cl) → B(C6F5)3 (1), germaester (i-Bu)2/s

The phosphinoborane adduct H3P-B(C6F 5)3 can be deprotonated using LiN(SiMe3) 2 to give the phosphidoborate salt Li[H2PB(C 6F5)3], which was converted to the phosphidodiborates Li[H2P{B(C6F5) 3}2] and Li[H2P(B(C6F 5)3}{BH3}] by treatment with an equivalent of B(C6F5)3 or Me2S-BH3, respectively. A series of anions of the form [RR'P{M(C6F 5)3}{BH3}-, where R=R' = Ph or R= 1Bu, R'=H, and M = B or Al, were prepared (through treatment of salts Li[RR'P(BH3)] with the corresponding Lewis acid) and characterized using multinuclear NMR, elemental analysis and X-ray crystallography. The solid state structures of [Li(Et2O)x][Ph2P{M(C 6F5)3}{BH3}] exhibit η2-bonding of the BH3 group to the cationic lithium center. The attempted preparation of an analogous series with amide cores of the form [R2N{B(C6F5)3}(BH 3)]- proved unsuccessful; among the competing reaction pathways hydride abstraction occurred preferentially to yield Li[HB(C 6F5)3] and dimers or higher oligomers with the composition (R2NBH2)n.

The chemistry of frustrated Lewis pairs derived from N-heterocyclic carbenes and a number of Lewis acids has been probed. The combination of 1,3-bis[2,6-(di-iso-propyl)phenyl]-1,3-imidazol-2-ylidene (IDipp) (1) with B(C6F5)3/su

(Chemical Equation Presented) Size matters: The frustrated Lewis pair derived from B(C6F5)3 and the sterically encumbered N-heterocyclic carbene N,N′-tBu2C3H 2N2 (1) cleaves dihydrogen heterolytically to give a imidazolium borate (see scheme, left), and cleaves amine N-H bonds to form aminoborate salts (right) or aminoboranes.
