Research Teams and Partnerships: Trends in the Chemical Sciences. Report of a Workshop

The Chemical Sciences Roundtable (CSR) used to be demonstrated in 1997 by means of the nationwide study Council (NRC). It presents a science-oriented, apolitical discussion board for leaders within the chemical sciences to debate chemically similar concerns affecting govt, undefined, and universities. prepared through the NRC's Board on Chemical Sciences and know-how, the CSR goals to bolster the chemical sciences by way of fostering conversation one of the humans and organizations-spanning undefined, executive, universities, associations-involved with the chemical firm.

Electrodeposition: Theory and Practice

184 A similar reaction involving bis(dimethylstibino)methane (Equation (92))184 or 1,3-bis(diphenylstibino)propane (Equation (93))185 resulted in a complex with two Fe(CO)4 fragments. 38 A). 190 The products from the R–I reactions contained four-coordinate SbR or SbR2 fragments with the other coordination sites occupied by Fe(CO)4 groups, whereas the reactions with the organic dihalides were more complicated. For 1,2-dibromoethane, a halogenated antimony complex was observed. With Cl(CH2)3Br, a monoalkylation product as observed for the R–I reactions was obtained along with a dialkylation product in which both the antimony and the iron were bonded to carbon (SbFeC3 ring).

For the related complex with L ¼ P(pyrrolydinyl)3, only the trans-form was observed. The enthalpies of reaction for this series gave a good linear correlation to the CO stretching frequency of the diaxial isomer, a measure of the electronic properties of the phosphine ligands. 155 Table 3 lists the various combinations of L and L9 that have been produced. The 2JPP values of the 31P{1H} NMR spectra exhibited a strong negative correlation with the sum of the phosphine pKa values. This allows for the prediction of 2JPP values for transFe(CO)3L2 complexes.

In this way, the complexes (OC)4FeL with L ¼ Me2PCH2B(OMe)2, Me2PCH2B(NMe2)Cl, Me2PCH2B(NMe2)2(NHMe2), Me2PCH2B(NMe2)2(NHMe2), Me2PCH2BCl2(NHMe2), and Me2PCH2BH2(2,4,6-C5H2N), as well as the anionic complex Li[Fe(CO)4Me2PCH2BH3], were prepared. Photolysis of (OC)4Fe{Me2PCH2B(OMe)2} with HSiPh3 led to oxidative addition and the formation of HFe(CO)3(SiPh3){Me2PCH2B(OMe)2}. 140 The intermediate complex depicted in Scheme 41 was proposed, but no evidence for it was observed by NMR. 140 The crystal structure of [Fe(CO)4(P4O6)] was reported—the first single crystal X-ray data for a transition metal complex containing P4O6.
