The conversion of methyl oleate by cross-metathesis with ethylene using readily accessible supported group VI oxo species was addressed. TON up to 500 and 5000 were achieved using bisgrafted tungsten- and molybdenum based systems, respectively (≡SiO)2M(═O)R2 (M = W, R = CH2SiMe3, M = Mo, R = CH2CMe3). In the case of molybdenum, these results are comparable to those obtained by Mo-based systems in homogeneous catalysis. Optimization studies showed that ethylene pressure plays a major role in these systems, with inhibition at high pressure resulting from degenerated metathesis involving ethylene and α-olefins.

易获得的负载型VI族负载型羰基催化剂催化可再生油酸甲酯的乙醇分解
提出了通过使用易获得的负载的第VI族氧代物质与乙烯进行交叉复分解来转化油酸甲酯的方法。TON高达500和5000使用bisgrafted钨和钼为基础的系统，分别为（≡SiO）实现2 M（= O）R 2（M = W，R = CH 2森达3，M =钼，R = CH 2 CMe 3）。在钼的情况下，这些结果与在均相催化中通过钼基系统获得的结果相当。优化研究表明，乙烯压力在这些系统中起主要作用，由于涉及乙烯和α-烯烃的简并复分解而导致的高压抑制作用。
