Synthesis and Pd(II) Complexes of an Unsymmetric and Flexible Ferrocene Bisphosphine

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Insertion of flexible spacers into the pivotal C(ferrocene)P bonds in dppf increases flexibility of the resulting homologated ligands and lowers their tendency to coordinate as P,P′‐chelating ligands. To expand the family of flexible homologated analogs of 1,1′‐bis(diphenylphosphino)ferrocene, the unsymmetric bisphosphine 1‐(diphenylphosphino)‐1′‐[2 ...

Microstructural Features of Austenite Formation in C35 and C45 alloys [PDF]

open access: yesMetallurgical and Materials Transactions A, 2007
The microstructural evolution during continuous heating experiments has been studied for two C-Mn steels with carbon contents in the range 0.35 to 0.45 wt pct using optical microscopy, scanning electron microscopy (SEM), and electron probe microanalysis (EPMA). It is shown that the formation of the austenitic phase is possible in pearlite as well as in
