REACTIONS INVOLVING TRANSITION METALS. XVII. REACTION OF ORGANIC HALOGEN COMPOUNDS WITH 2 AND 2 (S = CH2Cl2, THF)
The complexes 2 and 2 (S=CH2Cl2, THF) have been shown to react with CXCl3 (X=Cl, H) to form with generation of both dichlorocarbene and trichloromethyl radical.Reaction of 2 with CF3I, allyl- and benzyl-halides takes a different course giving organic coupling products and .The THF solvate complex also causes coupling of gem-dihalides, and dehalogenation of vic-dihalides to produce alkenes.Possible mechanisms for these reactions are discussed.

THERMISCHE STABILITAET VON BIS(ALK-2-ENYL)ZINK-VERBINDUNGEN
The dialk-2-enylzinc compounds I-III react slowly at 20 to 50 deg C by addition of the Zn-C bond to the C=C bond of an alk-2-enyl group to give oligomers from which the alkenes XIII-XV are released on hydrolysis.For I-III homolytic cleavage of the Zn-Callyl bond, followed by coupling of the allyl radicals to give the alkadienes V-VII, IX and XI predominates above 50 deg C.IV decomposes mainly homolytically even at 20 deg C.
