"Reaction of 2,3,4-trichloro-1-butene with phosphoric and nitrogen
nucleophiles was carried out," investigators in Yerevan, Armenia report
(see also General Chemistry).

"In the reaction with allyldiphenylphosphine
1,4-bis-(allyldiphenylphosp honiochlorido)-1,3-butadiene was obtained,
with tributylphosphine, allyldimethylamine and trimethylamine
respective 1,4-bis-onium salts with 2-chloro-2-butenylene
group. Reaction with trimethylamine proceeded with formation
of monoammonium salt with 3,4-dichloro-2-butenyl group," wrote
M.Z. Ovakimyan and colleagues.

The researchers concluded: "It is noteworthy that 1,4-splitting of
1,4-bis-(trimethylammoniochlorido)-2-butene at the action of sodium
methoxide occurs with involvement of the less labile hydrogen atom."

Ovakimyan and colleagues published their study in Russian Journal
of General Chemistry (Reaction features of 2,3,4-trichloro-1-butene
with phosphoric and nitrogen nucleophiles. Russian Journal of General
Chemistry, 2008;78(11):2052-2055).
