ChemInform Abstract: PREPARATION AND VIBRATIONAL SPECTRA OF SOME ESTERS AND CHLORIDES OF ANTIMONOUS ACID

Abstract

Antimonigsäure‐triäthylester (I) kann mit Acetylchlorid (II) zu 0,0‐Diäthyl‐antinonigsäurechlorid (IIIa) bzw. dem Dichlorid (IIIb) umgesetzt werden.

Reactions of dithioxo-1,3,2?5,4?5-dithiadiphosphetanes with antimony(III) alkoxides

“…Bands in the region m 619-624 cm ‫1מ‬ are assigned to the Sb-OC valence vibrations of two alkoxy groups that remain attached to the antimony atom of 3a,b [18]. Bands in the region m 687-673 cm ‫1מ‬ are assigned to the P‫ס‬S valence vibration.…”

Derivatives of trivalent phosphorus in the synthesis of glycerophosphatides and related phospholipids

“…91 -92 It is of interest that the glycerophosphepan is a stable compound, while its analogues, containing chlorine, dialkylamino-groups, and other very simple substituents at the phosphorus atom, are very labile and readily oligomerise. 214 " 218 The last factor explains the low effectiveness of the synthesis of glycerophosphepans via an alternative scheme consisting in the phosphorylation of substituted glycerols by the chloro-and dialkylamino-phosphepans already mentioned. 91 ' 92 Glycerophospho(III)cyclanes are promising intermediates in the synthesis of different types of phospholipids.…”
