	Abstract	The structures o f two new pyoverdins (G M -I and G M -II) isolated from the culture medium of Pseudomonas fluorescens have been elucidated by spectroscopic methods and degradation studies. The pyoverdins consist o f a chrom ophore which could be identified as (1 S)-5-amino-2,3-dihydro-8,9-dihydroxy-1 H -pyrim ido[l,2-a]quinoline-l-carboxylic acid substituted at the amino group with a 3-carboxypropanoyl or a succinamoyl residue and at the carboxy group with the N-terminus o f D -A l a -D -L y s —G l y -G ly -D -t h r e o -(O H) A s p -D -G lu -D -S e r — L -A l a -D -A l a -D -A l a -L -A l a -L -N 5-(O H)O rn .

	Title	Formation of r71-P-(2-Phosphinophenol)Ni(0)(PMe3)3 and Oxidation to cjs/fraws-Bis(2-phosphinophenolato)nickel(II) Complexes
	Abstract	o-Phosphinophenols 1 (P ^ O H) react with equimolar amounts of Ni(PMe3)4 at low tempera tures to give yellow Ni(0) complexes such as [(HO~P)Ni(PMe3)3] 2a with only P coordination of the P ^ O H ligand. Oxidation of solutions of 1 and Ni(PMe3)4 by dioxygen leads to brown bis(o-phosphinophenolato-P^O)nickel chelate complexes 3a-d. Structure elucidation by NM R is consistent with a m-square planar geometry for 3a-c and a rrans-square planar solution struc ture of the terr-butylphenylphosphino derivative 3d. The geometric isomers were distinguished by different ranges of phosphorus coordination shifts and 3lP-l3C-2 and 3IP-13C-1 coupling

	Abstract	A new isopropyl benzene derivative named as zatatriol (5) and two synthetically known compounds (2 and 7) having the same skeleton have been isolated from the hexane soluble part of a Lamiaceous plant Zataria multiflora. In addition to 2, 5 and 7, som e known constitu ents: p-cym ene (1), thymol (3), thymol methyl-ether (4) , /3-sitosterol, stigmasterol, oleanolic acid, betulinic acid, and hexadecanoic acid have also been isolated from the same source. Structures of the isolated constituents were elucidated with the aid of NM R spectroscopy.
