Organotrifluoroborates serve as coupling partners during transmetalation in the Suzuki-Miyaura reaction but require hydrolysis prior to the coupling reaction. Their anionic nature allows study of their hydrolysis by electrospray ionization mass spect

Chromate conversion coating is an efficacious and fast means of protecting metal parts from corrosion, but problematic in that it uses the toxic and carcinogenic chromic acid as the reagent. This short report covers some key considerations and altern

The reaction of Ph2P(DIPP) NH with AlMe3 cleanly gives an aluminum amide complex that crystallizes as a centrosymmetric dimer with a six-membered Al-N-P-Al-N-P ring. In aromatic solvents the dimer remains intact but the Al-P bond is readily broken up

Chemistry students are often introduced to the concept of atomic orbitals with a representation of a one-dimensional standing wave. The classic example is the harmonic frequencies which produce standing waves on a guitar string; a concept which is ea

Electron ionization (EI) is a reliable mass spectrometric method for the analysis of the vast majority of thermally stable and volatile compounds. In direct EI-MS, the sample is placed into the probe and introduced to the source. For air- and moistur

Reduction of red Cp2TiCl2 (Cp = cyclopentadienyl) with zinc dust in acetonitrile produces a blue solution of [Cp2Ti(NCMe)2]+, which when exposed to air rapidly discolors to bright yellow. This behavior makes the blue solution a handy visual indicator

Syntheses and crystal structures of the monomeric bora-amidinate (bam) complexes DIPPNBN-Mg·(THF)3 and DIPPNBN-Ca·(THF)4 are presented; DIPPNBN = HB[N(2,6-iPr2-C6H3)]2. The simplicity of their 1H NMR spectra in THF-d8 suggest that their monomeric s

Organocalcium compounds have been reported as efficient catalysts for various alkene transformations. In contrast to transition metal catalysis, the alkenes are not activated by metal-alkene orbital interactions. Instead it is proposed that alkene ac
