Platinum Olefin Coördination Compounds. I. The Structure of Dicyclopentadienedichloroplatinum(II)

Abstract

Temp, for dehydration, °C. Ni2 + Ni(glycine)2-2H20 795 2.12 2.72 135 ~140 Cu2 + CuS04'5H20 875 1.98 2.75 220Cr3 +[Cr(ox)2(H20)2]K-3 965 2.02 2.66 High H20 1012 2.72 increases in the same order. As is shown by the M-OH2 and O-H-O distances, the effects of coordination and hydrogen bonding are also increasing in the same order. Therefore we conclude that a cooperative effect of coordination and hydrogen bonding is responsible for the shift of the band and the rise of temperature of dehydration.Although the vibrational mode of the band is not yet determined, it is attributable to either one of the modes among wagging, twisting and rocking vibrations. A detailed study of the nature of this band is now in progress and will be reported later together with the measurements in the KBr region.Acknowledgment.-The authors wish to express their sincere thanks to Mr. N. Ooi of the Sumitomo Chemical Company for aid in obtaining the spectra.

Synthesis and structural characterization of a new polysiloxane with second‐order nonlinear optical effect

“…The p ‐nitrobenzenediazonium fluoroborate was synthesized following a procedure described in the literature 10. Dicyclopentadienedichloroplatinum was synthesized according to the method of Doyle ans Jonassen 11 . N ‐Allylcarbazole was prepared as reported previously 6 .…”

A new postfunctional method to synthesize C60‐containing polysiloxanes

“…Pyridine was dried over and distilled from CaH 2 under an atmosphere of dry nitrogen. Dichlorodicyclopentadiene platinum was prepared following the literature procedure 8. All other reagents were used as received.…”

“…Dichlorodicyclopentadiene platinum was prepared following the literature procedure. 8 All other reagents were used as received. All the reactions were carried out in a dry nitrogen atmosphere using Schlenk technique.…”

A novel synthetic strategy to develop second‐order nonlinear optical polysilanes for potential photorefractive effects

“…Dicyclopentadienedichloroplatinum is synthesized according to the method of Doyle. [12] N-allyl-N-ethylaniline is prepared from N-ethylaniline and allyl iodide. Methylphenyldichlorosilane is synthesized via traditional Grignard reaction of methyltrichorosilane and phenyl magnesiumbromide.…”
