Chem., 306(2), 257-65 (English) 1986. CODEN: JORCAI. 16136-84-8 and 16136-85-9 are also in the experiment. ISSN: 0022-328X. DOCUMENT TYPE: Journal CA Section: 23 (Aliphatic Compounds) Section cross-reference(s): 22 Radical-promoted Bu3SnH redn. of CH2:CHCHCl and (E)- or (Z)-ClCH2CH:CHCl yields a mixt. of CH2:CHCH2Cl and (E)- and (Z)-MeCH:CHCl. The palladium-catalyzed redn. yields regiospecifically MeCH:CHCl with a none thermodn. Z to E ratio that remains const. at ~ whatever the starting dichloropropene. The results strongly support a polar p-allyl mechanism for the catalytic reactions. .

An important limitation in the reactions of 1-chloro-1-alkenes with n- or s-butyllithium: An important limitation in the reactions of 1-chloro-1-alkenes with n- or s-butyllithium. Nelson, Donna J. (Dep. Chem., Univ. Oklahoma, Norman, OK 73019, USA). J. Org. Chem., 49(11), 2059-61 (English) 1984. CODEN: JOCEAH. 16136-85-9 and 7611-87-2 which are cas registry numbers are also used here. ISSN: 0022-3263. DOCUMENT TYPE: Journal CA Section: 23 (Aliphatic Compounds) Contrary to previous reports, the reactions of 1-chloro-2-alkyl-1-alkenes with n- or sec-butyllithium do not lead to stable Li derivs. which could be synthetically useful in reactions with electrophiles. The reaction of 1-chloro-2-methyl-1-propene is plagued by polymn. at lower temps. and by fast reaction with a second equiv of base to give 2-methyl-2-heptene at higher temps. However, the reactions of simple 1-chloro-1-alkenes apparently proceed through alkynyllithium derivs. analogous to those reported for 1-chlorostyrene. .
