Two subvalent, redox-active diborane(4) anions, [3]4- and [3]2-, carrying exceptionally high neg. charge densities are reported: Reduction of 9-methoxy-9-borafluorene with Li granules without stirring leads to the crystallization of the B(sp3)-B(sp2) diborane(5) anion salt Li[5]. [5]– contains a 2,2′-biphenyldiyl-bridged B-B core, a chelating 2,2′-biphenyldiyl moiety, and a MeO substituent. Reduction of Li[5] with Na metal gives the Na+ salt of the tetraanion [3]4- in which two doubly reduced 9-borafluorenyl fragments are linked via a B-B single bond. Comproportionation of Li[5] and Na4[3] quant. furnishes the diborane(4) dianion salt Na2[3], the doubly boron-doped congener of 9,9′-bis(fluorenylidene). Under acid catalysis, Na2[3] undergoes a formal Stone-Wales rearrangement to yield a dibenzo[g,p]chrysene derivative with B=B core. Na2[3] shows boron-centered nucleophilicity toward Bu chloride. Na4[3] produces bright blue chemiluminescence when exposed to air. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Quality Control of Tetramethylammonium chloride).
Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Quality Control of Tetramethylammonium chloride
