摘要：

The cyclic ketones can be converted to their aldol-type condensation products by the W(CO)(6)/CCl4/UV system. The reaction was monitored by recording the IR and GC-MS spectra of the reaction mixture. The results support a mechanism that includes an intermediate carbene complex of tungsten. (C) 2000 Elsevier Science S.A. All rights reserved.
