	Title	Beiträge zur Chemie des Phosphors, 84 [1] 1.2.3-Trimethyl
	Abstract	The reaction of K2(PMe)4 • 2 THF with eis-1,2-dichloroethylene yields the hitherto unknown cyclocarbaphosphanes 1,2,3-trimethyl-1,2,3-triphosphole, (PMe)3C2H2 (1), and 2,3,4,6,7,8-hexamethyl-2,3,4,6,7,8-hexaphosphabicyclo[3,3,0]octane, (PMe)6C2H2 (2). Besides, (PMe)s, (PMe)4CH2, (PMe)3C2Hi, and the new six-membered heterocycle (PMe)2(C2H2)2 are formed. The cyclocarbaphosphanes 1 and 2 were characterized by elemental analysis, mass, IR, Raman, and NMR spectra. For the bicyclic compound 2 two diastereomers were obtained and separated. They differ in the position of the methine hydrogens and of the methyl substituents (eis-2 and trans-2). Compound 2 is also produced in the reaction of K2(PMe)4 • 2 THF with £rans-l,2-dichloroethylene whereas with 1,1,2,2- tetrachloroethane mainly (PMe)s is formed. In 1 and in each of thefive-memberedrings of cis-2 and trans-2 the methyl substituents at adjacent phosphorus atoms are situated on opposite sides of the ring.

	Title	Synthesis and Structure of 1,2,3-Thiadiazol-and 1,2,3-Selenadiazol-Pentacarbonyl-Complexes of the Elements Chromium and Tungsten
	Abstract	From the reactions of (THF)M(CO)5 (M = Cr, W) with 4-phenyl-l,2,3-thiadiazol, 4-methyl-5-carboxylic acid-l,2,3-thiadiazol, 4-methyl-5-carboxylic acid ethyl ester-1,2,3-thiadiazol and 4-methyl-l,2,3-selenadiazol, pentacarbonyl-complexes are obtained as air stable compounds. IR spectra of products of similar reactions with M = Mo provide some evidence of the formation of analogous complexes. The thiadiazol complexes are also accessible directly, by photochemical displacement of carbonmonoxid in THF from the parent carbonyl. The X-ray structures of pentacarbonyl-(4-phenyl-l,2,3-thiadiazol)-tungsten and pentacarbonyl-(4-methyl-l,2,3-selenadiazol)-chromium show the coordina-tion of the ligand to the pentacarbonyl-metal-fragment via the nitrogen in position 2.

	Abstract	Piperidine-N-oxyboranes and 2,2,6,6-Tetram ethylpiperidine-N -oxyboranes have been p re pared starting from halogenoboranes by three methods: a) By reaction with N-hydroxypiperidine and triethylam ine; b) by cleavage of the Si —O-bond in piperidine-N-oxy-trim ethylsilanes and c) by reaction with metallated piperidine-N-oxy compounds. Diboryloxides and diborylamides, resp., are obtained upon reaction of piperidine-N-oxy-brom oboranes with hexamethyldisiloxane and hexamethyldisilazane. Steric influences upon reac tivity and spectroscopic properties are discussed. The com pounds are characterized by elem ental analysis, mass and NMR spectroscopy ('H , "B , 13C , 14N , 29Si). A n X-ray analysis has been carried out for tris(2,2,6,6-tetram ethylpiperidine-l-oxy)borane 13.

	Abstract	The thiocarboxamidocinnamonitriles (2) reacted with 2-hydrazinothiazol-4(5//)-one (3) to afford the corresponding pyrano[2,3-d]thiazoles (6). Compounds 6 were used for the synthe sis of several new annelated pyran, thiazole, 1,2,4-triazole and 1,2,4-triazine derivatives via their reactions with chloroacetic acid, ethyl chloroformate, diethyl oxalate and acetylacetone. Structures were established based on elemental and spectral data studies. Some of the newly synthesized heterocyclic derivatives were tested for their antimicrobial activity.

	Abstract	The IR and Raman spectra of the ten brom o-iodo-rhenates(IV) [ReBr"I6_"]2 -, n = 0 -6 , including the geometrical isomers for n -2,3,4, have been recorded at 80 K. The vibrational spectra are com pletely assigned according to point groups O h, D 4h, C4v, C3v, and C2v, as supported by normal coordinate analyses based on a general valence force field. Due to the different mms-influences Br < I in asymmetric axes B r '-R e -I ', the R e -I ' bonds are strengthened and the R e -B r ' bonds are weakened, as indicated by valence force constants, for R e -I ' on average 8,5% higher and for O s -B r ' 8,3% lower, as compared with the values calculated for symmetric I -R e -I and B r -R e -B r axes, respectively
