The carbon-13 n.m.r. spectra of derivatives of the branched-chain sugars apiose and dendroketose, and of other furanose sugars, are reported. The study has permitted assignment of the configuration at the branching carbon atom and at the anomeric center in the dendroketose derivatives.

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 unusual features of the proton and 19F nuclear magnetic resonance spectra of (CH3)3SnCF2CFHCF3, arising from the asymmetry about the β-carbon atom, are discussed in terms of the molecular stereochemistry. Data for (CH3)3SnCF2CF(CF3)Sn(CH3)3, (CH3)3SnCF2CF2H, and (CH3)3SnCF2(CF2)2CF2H are also presented.
