摘要

Just because carbon jumps off a bridge, doesn't mean that tin will too. Scientists have conducted an experiment that attaches a simple hydrocarbon to triple-bonded tin atoms, violating a well-established set of organic chemistry rules. The finding suggests that heavier elements don't behave the same way as carbon, a team reports in the Sept. 25 Science.rnIn the new work, tin atoms bonded to ethylene, a small molecule consisting of two carbon and four hydrogen atoms. Tin should, in principle, be chemically similar to carbon. But carbon does not undergo this same reaction.rn"I believe this is a reaction that could lead to further breakthroughs in fundamental science," says Lawrence Sita of the University of Maryland in College Park, who wrote a commentary on thernresearch in the same issue of Science. "This could be a launching point for a number of experiments."
