Ni-Catalyzed enantioselective reductive arylcyanation/cyclization of: N -(2-iodo-aryl) acrylamide

A Ni/(S,S)-BDPP-catalyzed intramolecular Heck cyclization of N-(2-iodo-aryl) acrylamide with 2-methyl-2-phenylmalononitrile was developed to give oxindoles with good enantioselectivities. We found that utilizing such an electrophilic cyanation reagent cou

Copper-catalyzed synthesis of alkynylphosphine derivatives: Unprecedented use of nucleophilic phosphorus compounds

A new and smooth approach towards alkynylphosphine derivatives is described. It relies on the unprecedented catalytic coupling of secondary phosphine boranes with alkynyl bromides using the CuI/1,10-phenanthroline couple.

Synthesis and structural characterisation of alkali metal complexes of heteroatom-stabilised 1,4- and 1,6-dicarbanions

A straightforward Peterson olefination reaction between either [{(Me 2PhSi)3C}Li(THF)] or in situ-generated [(Me 3Si)2{Ph2P(BH3)}CLi(THF) n] and paraformaldehyde gives the alkenes (Me2PhSi) 2C=CH2 (1) and (Me3Si){Ph2P(BH 3)}C=CH2 (2), respectively, in good yield. Ultrasonic treatment of 1 with lithium in THF yields the lithium complex [{(Me 2PhSi)2C(CH2)}Li(THF)n]2 (3), which reacts in situ with one equivalent of KOBut in diethyl ether to give the potassium salt [{(Me2PhSi)2C(CH 2)}K(THF)]2 (4). Similarly, ultrasonic treatment of 2 with lithium in THF yields the lithium complex [[{Ph2P(BH 3)}(Me3Si)C(CH2)]Li(THF)3] 2.2THF (5). The bis(phosphine-borane) [(Me3Si){Me 2(H3B)P}CH(Me2Si)(CH2)]2 (6) may be prepared by the reaction of [Me2P(BH3) CH(SiMe3)]Li with half an equivalent of ClSiMe2CH 2CH2SiMe2Cl in refluxing THF. Metalation of 6 with two equivalents of MeLi in refluxing THF yields the lithium complex [[{Me2P(BH3)}(Me3Si)C{(SiMe2) (CH2)}]Li(THF)3]2 (9), whereas metalation with two equivalents of MeK in cold diethyl ether yields the potassium complex [[{Me2P(BH3)}(Me3Si)C{(SiMe2) (CH2)}]2K2(THF)4]∞ (10) after recrystallisation. X-Ray crystallography shows that, whereas the lithium complex 5 crystallises as a discrete molecular species, the potassium complexes 4 and 10 crystallise as sheet and chain polymers, respectively.
