Although use of radio and stable isotope labels involving the trio of covalently-bonded nitrogenous functions in 3 and in 78, provided evidence that isocyano is the precursor of the isothiocyano and formamido groups [30, 81], it remains to be shown that a biosynthetic equivalent of the in vitro chemically-proven fusion process between isocyano and free sulfur (e.g., cf. Introduction) exists in the cells of sponges. In marine biota, various ionic forms of sulfur in a number of oxidation states, as well as organo-polysulfides are known. However, any association with the isonitrile group and a sulfated species has yet to be established. 

In addition, the adsorption properties of organo-LDHs may also be utilized in the preparation of new materials. The intercalation of Ceo molecules into the hydrophobic interlayer of an Mg/Al LDH with intercalated dodecyl sulfate anions has recently been reported [176]. It was found that heating the resulting compound under vacuum in order to decompose the dodecyl sulfate left Ceo molecules sandwiched between the hydroxide layers, although the crystallinity of the sample was poor. 

Recent work [50] has shown that in the presence of sulfate ions, SNF forms an organo-mineral compound with C3A, allows a greater dissolution rate of the CaS04, and alters the morphology of the hydration...

Organo Vinyl Tellurium (from Vinyl Tellurium Iodides) A solution of the vinyl tellurium iodide, prepared by addition of 0.25 g (1.0 mmol) iodine in benzene to the divinyl ditelluride (1.0 mmol) in 5 ml tetrahydrofuran at 0° under nitrogen, is added dropwise to a solution of the organo magnesium bromide in 10 m/ tetrahydrofuran at 0°. The mixture is stirred at 20° for 1 h, hydrolyzed with a saturated aqueous solution of ammonium chloride, extracted with diethyl ether, the extract dried with magnesium sulfate and evaporated. The product is chromatographed on silica gel with petroleum ether (30-60°)/ethyl acetate (9 1) as eluent. The following compounds were prepared in this manner (yields in parentheses are for the reactions with vinyl tellurium iodides) ... 

Formyl-3-thienyl Methyl Tellurium (Organo Lithium Method) A mixture of 55 mmol of butyl lithium and 7.8 g (50 mmol) of 4-formylthiophcnc ethylene acetal in diethyl ether is cooled at — 78° for 20 min. A solution of 14.5 g (50 mmol) of dimethyl ditellurium in diethyl ether is added dropwise until the orange color of the ditellurium persists in the mixture. The mixture is allowed to warm to 20° and is then poured onto ice/water. The product is extracted with diethyl ether, the extract is dried with anhydrous magnesium sulfate, filtered, the solvent is distilled from the filtrate and the residue is distilled under vacuum yield 6.3 g (50%) b.p. 120°/0.8 torr m.p. 55°.

The alkyl phosphoric acids were first recognized as excellent actinide extractants because dibutyl phosphoric acid existed as an impurity in TBP (8). They extract well from unsalted solutions and from systems such as sulfate in which TBP is ineffective. Organo-phosphorus acids are thus suitable for uranium hydr metallurgical applications where ore is leached with sulfuric acid. The Dapex process is an example in which bis(2-ethylhexyl) phosphoric acid (HDEHP) is used alone or in synergistic combination with neutral organophosphorus compounds for uranium and vanadium recovery (9,10).

While the salts of lithium such as carbonate, sulfate, nitrate and chloride do not require special equipment for handling, all products derived from metallic lithium (e.g., organo-lithium compounds, lithium aluminum hydride) have a high reactivity and may even ignite when exposed to (humid) air. Therefore, production and handling must be carried out under an inert gas (e.g..
