Studies on models synthesized by stereochemically controlled routes show that the central triene chromophore in the common cis isomer of phytoene has the irans,cis,trans configuration, and that the phytoene from Flavobacterium dehydrogenans consists mainly of the all-trans isomer. Capsorubin, with the natural configuration at all four chiral centres, has been synthesized from (+)-camphor. Sever...

Alkyldifluorophosphites, ROPF2 (R = ^-substituted benzyl group, neopentyl, 1-adamantyl) have been obtained by a new method, involving reaction of the appropriate alkyl trimethylsilylether, ROSiMe3 with chlorodifluorophosphine, PF2C1. Reactions of these difluorophosphites with platinum(II) complexes of the type [LaPtCla] (L = PEt3, PPI13) led to products such as irans-[L2PtCl(POF2)] and {[p-XC6H...

The biphenyl-bridged. chiral zirconocene complex rac-2.2' -biphenyl-bis( 3.4-dimethylcyclopentadienyl I zirconium dichloride catalyzes the reaction of 1.6and 1,7 -dienes with excess dibutyl magnesium to bis( butyl-magnesio-methyl '-substituted cycloalkanederivatives. Analogous reactions occur with butyl magnesium chloride and with heteroatom-t.:Ontaining dienes. The preference of 1.6-dienes for...

a response to the problem of irans backwardness preoccupied the minds of intellectual and political forces. since irans failure from russia while different domestic and external factors caused to defeat, differend and even contending views concerning irans backwardness played a key role in these failures. these diverse and contending views which arised at first in compilation of laws and establ...
