THE SYNTHESIS AND PROPERTIES OF ANTIMONY-SULPHUR AND ANTIMONY-OXYGEN LIGANDS
Levason, William,Sheikh, Baharuddin
, p. 1 - 10 (1981)
The synthesis and properties of a series of potentially bi-, tri- and tetra-dentate ligands containing various combinations of antimony and sulphur and antimony and oxygen donors, is described.Included are SbPhn(o-C6H4OMe)3-n (n = 0, 1, 2); SbMe2(o-C6H4OMe); SbPhn(o-C6H4SMe3)3-n (n = 0, 1, 2); SbMe2(o-C6H4SMe); MeS(CH2)3SbR2 (R = Me, Ph) and S(CH2CH2CH2SbPh2)2.Attempts to prepare ligands with dimethylene backbones including (R2SbCH2CH2)2S (R = Me, Ph) failed.The ligands were characterised by analysis, 1H NMR and mass spectra, and by the preparation of quaternary derivatives.

Ester groups are reduced very efficiently in sulfur-containing molecules situated at close proximity to the ester group. We have used this procedure to regioselectively, efficiently and in high yield reduce an ester group in the presence of another ester group further removed from the sulfur atom.

Sulfoboration of Cyclic Ethers - A Preparative Route to Mercaptoalkanols and Bis(hydroxyalkyl) Sulfides
Koester, Roland,Kucznierz, Ralf
, p. 835 - 842 (2007/10/02)
Bis(1,5-cyclooctanediylboryl) sulfide (1) reacts slowly with the cyclic ethers A-D to give O,S-bis(9-BBN)mercaptoalkanols 2a-d in excellent yields.From oxetane (E) and 1, however, 2e is obtained rapidly, which further reacts with E to yield the bis(9-BBN-oxypropyl) sulfide 3ee. 2a and c react with E to form the mixed thioethers 3ae and 3ce, respectively.The methanolysis of 2a-e leads to the O-(9-BBN)mercaptoalkanols 4a-e.The compounds 2 and 3 react with acetylacetone or with 2-aminoethanol to yield the mercaptoalkanols 7a-c, e and the bis(hydroxyalkyl) sulfides 8ae, 8ce and 8ee, resp., in high yields beside the 9-BBN-chelates 5 or 6.Key Words: Ethers, cyclic, cleavage of / Sulfoborations / Mercaptoethanols, 9-BBN derivatives of / Sulfides, bis(hydroxyalkyl), 9-BBN derivatives of
