Pp. 1095 - 1098
TEXT~ The authors have previously (Ref. 1) established that lithium-
dialkyl-amides are added to vinyl-acetylene-hydrocarbons, and that
allene- or acetylene-amines are formed after the adduct has been treated
with water. The authors wanted to study the behavior of other compounds
of the type R 2E - Li under the same conditions (E - an element of the
V. g-roup of the periodic system). To do this they analyzed the reaction
of vinyl-acetylene and two of its homologe; vinylmethyl and vinyl
ethylacetylene, with lithiumdiethyl- and lithiumdibutylphosphides. As
expected, the addition of lithiumphosphides tjok place in all three
possible ways (I), (II), and (III). On the other hand in the case of

winylmethyl- and vinylethyl-acetylene, tertiary &Ilene phosphines (11)
formed almost without exception. Tertiary phosphine which formed by
treatment of the adduot of lithiumdibutylphosphide on viaylacetylene
undoubtedly contained 1-dibutylphosphinobutine-5 according to the
spectral data, Some 40% acetylene was found In It by the usual method.
Vinylmethyl- and vinylethylaoetylene behave in the same way in the re-
action with lithium phosphides, while vinylethylacetylene gives allene
products, and vinylmethylacetylene gives mainly the dimer and poly-mers-
on the reaction with lithiumalkylamidee. Considerable quantitles of
hIgh-bolling phosphorus-containing products are also formed in all
nasea, as well as tertiary phosphines. The authors suppose that thsy
are higher telomere of the phosphines isolated from them., Lithiumdi
alkylphosphides react easily with halogen derivatives, producing
saturated tertiary phosphines, The authors obtained diethylbutylphos
phine from the action of lithiumdiethylphosphide on butylchloride
Tributylphosphine formed in a similar way from 11thiumd1butylphosphide
and butylehloride. No alkylchloride remained from the reaction on the
production of lithiumalkyls The phosphineB with an al!ene group are
described here for the first time The tertlar7 ailene phospnines

graphs of wear against load, wear being assessed by diameter of
wear-scar. The tests in argon atmosphere display considerable
variation in seizure load and siiape of wear curve. In general,
however, in argon the seizure loads are low and the wear is small
at loads below the seizure loads. The seizure is easily broken
down. The test results of _ydrocarbons in argon are similar to
those observed for low-sulphur lubrizating oils. The behaviour
observed is attributed to the prejen-e of traces of oxygen or

strength. The present authors intended to examine the trimerization
mechanism of copolymers containing pyridine ring, as well as the
possibility of their reversible conversion to form linear polymers. A
reversibility has already been observed in the acid treatment of trimers
containing azomethIne group in the side chain, obtained by polymerizati8n
of Schiff's bases with vinyl group, as well as in KOH vulcanization
