摘要
p-Xylylene-bis-(triphenylphosphonium chloride) reacted with terephthalaldehyde in the presence of lithium ethylate to yield a decamer of poly-p-xylylidene (II, n = 9, X = CHO). Treatment of (2-methoxy-5-methylalbenzyl)-triphenylphosphonium chloride with base produced the methoxy derivative of poly-m-xylylidene (V), (p-Hydroxyphenyl)-triphenylphosphonium bromide on treatment with base failed to yield poly-p-phenylene.
