Triphenylphosphine and triphenylarsine derivatives of W(CO)4(NO)X (X = Cl, Br, I) have been prepared. These compounds have the form mer- W(CO)3(NO)LX, cis-W(CO)2(NO)L2X, and trans-W(CO)2(NO)(PPh3)2X. A trans complex with triphenylarsine could not be prepared. Further substitution with either ligand was not achieved. In addition, the tri(ortho-, meta-, and para-)tolylphosphine and arsine complexes of W(CO)4(NO)I have been isolated. Their nuclear magnetic resonance spectra indicate interaction between neighbouring ligands in some cases, and suggest that possible rotation about the metal-phosphorus and arsenic bonds may occur in these compounds.

Methylmercuric nitrate reacts with pyridine-2(lH)-thione (C5H5NS) in acetone to give methyl-(pyridine-2(1H)-thione)mercury(11) nitrate, [MeHg(C5H5NS)] NO3. This complex reacts with sodium bicarbonate in acetone to give methyl(pyridine-2-thiolato)mercury(11), MeHg(C5H4NS).Infrared, Raman, and nuclear magnetic resonance spectra indicate that MeHgH is bonded to sulphur in both complexes, and that protonation of nitrogen occurs on reaction of MeHg(CsH,NS) with nitric acid to give [MeHg(C5H5NS)] NO3.

The 13C n.m.r. spectra of the 2-acetamido-2-deoxy-D-hexoses and some 3-O-acetyl and 1-phosphate derivatives are assigned and discussed. To facilitate the interpretation of the spectra, an initial assignment of the resonances in the spectrum of 2-acetamido-2-deoxy-D-glucose was required. For this purpose, both the 3-2H and 4-2H derivatives of this acetamido-hexose were synthesized. These syntheses are reported together with those of 2-acetamido-3-O-acetyl-2-deoxy-D-glucose and 2-acetamido-2-deoxy α- and β-D-glucose-1-phosphate. These model compounds were used to study substituent effects related to the 2-acetamido-2-deoxy-D-hexose-containing polysaccharide antigens of N. meningitides.
