摘要

During studies aimed at developing an understanding of the factors affecting the telomerization of butadiene with water in the presence of C02, we unexpectedly found that, under certain conditions, 2-vinylmethylenecyclopentane 1 can be formed in high yield and selectivity, according to Scheme 1. This result appears rather unusual in palladium-diene chemistry where, on the other hand, it is well known that C02 displays an activating effect both in butadiene ...
