The infrared spectra of dithiocarbamato and N-alkyldithiocarbamato complexes with various metals have been obtained in the range between 4000 and 280 cm-I • The spectra of their deuterated forms have also been obtained to confirm the band assignments. A normal-coordinate analysis has been carried out for the 1:1 (metal/ligand) model of the dithiocarbamato Pt ll complex. The results indicate that the Pt-S stretching bands are at 375 and 288 cm-I and the corresponding Pt-S stretching force constant is 2.1 X1()5 dyn/cm. The effects of changing the metal and of alkyl substitution on the electronic structure of these compounds have been inferred from the infrared spectra. . TABLE III. Force constants (10· dyn/cm).

“…The synthesis of XeF 6 was reported for the first time in 1962,1 followed by three later reports in 1963 2–4. It was observed fairly quickly that XeF 6 is a very good fluoride ion donor forming [XeF 5 ] + or [Xe 2 F 11 ] + salts.…”

New types of [XeF5]+ salts, i.e., NO2XeF5(SbF6)2 and XeF5[Cu(SbF6)3], are derived from reactions between XeF5SbF6 and NO2SbF6 or Cu(SbF6)2, respectively. The crystal structure of the former consists of [NO2]+ and [XeF5]+ cations and [SbF6]– anions. The main feature of the crystal structure of XeF5[Cu(SbF6)3] are rings of CuF6 octahedra that share apexes with SbF6 octahedra connected into an infinite tridimensional framework. This arrangement leads to the formation of cavities within which [XeF5]+ cations are located. Raman spectra of both [NO2]+/[XeF5]+ and [XeF5]+/Cu2+ mixed‐cation hexafluorido‐antimonates(V) are reported herein.

G. Closing Remarks situated, the hypoiodite reaction can lead to a homolytic substitution of iodine on the carbon by an oxy-radical. The action of lead tetraacetate on alcohols leads directly to high yields of tetrahydrofuran derivatives, without the formation of a "free carbonium ion", when all the participating centers are fixed in the arrangement which favors hydrogen abstraction. In the lead tetraacetate oxidation of alcohols in which the hydroxy groups and the attacked C-€3 bond are not fixed, acetoxylated or unsaturated 5or 6-membered cyclic ethers can be formed through intermediates with a carbonium character. Easily cleavable derivatives of homoallyl and homobenzyl alcohols are not suitable as starting materials for intramolecular substitution reactions, since in such cases the carbonyl-forming fragmentation competes successfully with the intramolecular hydrogen abstraction. This side reaction occurs in general when the carbon radical produced is stabilized. In the presence of acylates of tri-and tetravalent lead, the carbonylforming fragmentation may be reversible. The course of the intramolecular free-radical reactions can be changed by the addition of intermediately formed carbon radicals onto neighboring unsaturated systems such as C-C, C=O, or C EN groups. Received, October 9th, 1963 (A 372/169 IEI German version: Angew. Chem. 76, 518 (1964) Translated by Express Translation Service, LondonThe intramolecular substitution reactions of oxyradicals may be summarized as follows: In the photolysis of nitrites and hypochlorites only ligand transfers have been observed as primary processes (formation of 1,5-nitroso alcohols or 1,5-chlorohydrins). In the h,vpoiudite reaction, the principal process besides the ligand transfer (formation of 1,5-iodohydrins, which can then undergo intramolecular solvolysis, in the same way as the chlorohydrins, to yield tetrahydrofuran derivatives) is the oxidation of carbon radicals to carbonium ions. In contrast to the photolysis of nitrites and hypochlorites, in which only a single intramolecular substitution is possible, the same carbon atom may be doubly substituted in the hypoiodite reaction. The reason for this difference is that the hypoiodites are prepared from alcohols and split homolytically in situ, so that both the initially formed (monoiodinated) alcohols and the regenerated starting material can react further. The yields in the hypoiodite reaction are therefore generally higher than those of the analogous photolyses of nitrites or hypochlorites. The course of the reaction can be influenced by special steric relationships. If the reaction centers are suitably
