Abstract

A new example of [2+4] cycloaddition of the lowโ€coordinated diphosphaโ€analog of butadiene protected with a 2,4โ€diโ€tertโ€butylโ€6โ€methylphenyl group has been described. Xโ€ray structure investigations of monomer 4b and dimer 5a have been reported for the first time. ยฉ 2003 Wiley Periodicals, Inc. Heteroatom Chem 14:231โ€“234, 2003; Published online in Wiley InterScience (www.interscience.wiley.com). DOI 10.1002/hc.10123

The reactions of 2,3-dichloro-1,4-diphospha-1,3-butadiene, which is sterically protected with the 2,4,6-tri-t-butylphenyl group, with some nucleophiles, including alkyllithium reagents and lithium aluminum hydrides, afforded 1,2-diphosphinoacetylenes or 3-phosphino-1-phosphaallenes.

## Abstract Novel complexes [(C~5~Me~5~)~2~Ln][B(C~6~F~5~)~4~] (Lnโ€‰=โ€‰Pr, Nd, or Gd) were prepared, which in combination with ^__i__^Bu~3~Al efficiently induce highly 1,4โ€cisโ€specific polymerization of butadiene. The activity of the Gd complex/^__i__^Bu~3~Al system is high enough to exhibit good cat
