The disulfide intermediate was also hydrogenolyzed very efficiently at about 2-3 times the rate of the thiocyanate in selected solvents such as tetrahydrofuran at a lower temperature and pressure, as illustrated in Table 15.2. Of course, in the disulfide hydrogenolysis, no hydrogen cyanide was available as a coproduct to poison the palladium catalyst.

The addition of morpholine to 2,3-dihydrofuran in the presence of palladium(II) thiocyanate-bis(triphenylphosphine) yields 2-(morpholin-4-yl)tetrahydrofuran (276)303. Irradiation of mixtures of 2-(2-methylpropenyl)phenol (277) and alkylamines yields adducts, e.g. 278 with isopropylamine304. 

The reactions of lanthanide thiocyanates, nitrates, and chlorides with TPPO have been studied by Cousins and Hart (202, 203, 205). The reactions of lanthanide nitrates with TPPO in ethanol, acetone, ethylacetate and tetrahydrofuran are given in Fig. 1. The nature of the complexes isolated depends on the concentrations of the ligand and the metal ion, temperature of mixing, presence or absence of the seed of the desired complex, size of the cation, and the nature of the solvent. Tetrakis-TPPO complexes of Ce(III) and Nd(III) perchlorates have been reported (206, 207). Two of the perchlorates are coordinated to the metal ion in these complexes.

It was the first naturally occurring crown ether, and the earliest for which the antibiotic activity could be traced to its ionophoric properties (4). The actins give one-to-one complexes with many alkali and alkaline earth metal ions, with nonactin showing selectivity in the order NH4+ > K+ = Rb+ > Cs+ > Na+ > Ba2+ (5). The first X-ray crystal structure of an ionophore-metal complex was obtained from the nonactin-potassium thiocyanate complex (6). The potassium is bound by coordination to all four tetrahydrofuran oxygens and to the four ester carbonyl oxygens, which creates overall a "tennis ball seam" conformation to the carbon framework as it wraps around the metal.

Alkaline earth thiocyanates dissolved in nonaqueous solvents have received less attention [286-288]. Ionic pairs [M NCS ] and [M (NCS )2] usually cannot be distinguished by vibrational methods. However, dimeric species M2(NCS)4 are observed in calcium thiocyanate solutions in acetonitrile and in strontium and barium thiocyanates dissolved in a number of solvents (methyl acetate, tetrahydrofuran, or acetone). This association species seems to be absent in nonaqueous solutions of both beryllium [286] and magnesium [287,288] thiocyanates. The proposed structure of the barium thiocyanate dimer and the Raman v(CN) spectral region of a 1 M solution of Ba(SCN)2 dissolved in THF are shown in Fig. 20.
