    • The present invention provides a process for preparing a metal carbene complex of formula (I): wherein M is a transition metal atom selected from the group consisting of ruthenium, rhodium, iron , cobalt, osmium and iridium; L denotes neutral donor ligands ligated to said metal, such groups being the same or different; X is an anionic ligand; R1 and R2 are each independently selected from the group consisting of hydrogen, substituted or unsubstituted C1-C20 alkyl, substituted or unsubstituted C2-C20 alkenyl, substituted or unsubstituted cycloalkyl, substituted or unsubstituted heterocycloalkyl, substituted or unsubstituted aryl, substituted or unsubstituted heteroaryl, substituted or unsubstituted vinyl, a is 2 or 3 and b is 1 or 2, such process comprising reacting a sulfur ylide of the formula Ar 2 S=CR 1 R 2 or its precursor with an appropriate metal complex comprising a transition metal atom selected from the group consisting of ruthenium, rhodium, iron, cobalt, osmium and iridium, said metal complex being also in dimeric form, at a temperature between +80 °C and -80 °C, in an inert solvent and under inert atmosphere.
    • 本发明提供了制备式(I)的金属卡宾络合物的方法:其中M是选自钌,铑,铁,钴,锇和铱的过渡金属原子; L表示与所述金属连接的中性供体配体,这些基团相同或不同; X是阴离子配体; R 1和R 2各自独立地选自氢,取代或未取代的C 1 -C 20烷基,取代或未取代的C 2 -C 20烯基,取代或未取代的环烷基,取代或未取代的杂环烷基,取代或未取代的芳基, 取代或未取代的乙烯基,a为2或3,b为1或2,该方法包括使式Ar> 2 R 2或其前体的硫叶立德与合适的金属络合物反应, 选自钌,铑,铁,钴,锇和铱的过渡金属原子,在惰性溶剂中,在+ 80℃至-80℃之间的温度下,所述金属络合物也是二聚体形式,和 在惰性气氛下。

    • A system (10) and method (40) for efficiently reducing transcription error using hybrid voice transcription is provided. A voice stream (22) is parsed into utterances. An initial transcribed value and corresponding recognition score (113) are assigned to each utterance. A transcribed message (23) is generated and includes the initial transcribed values. A threshold is applied to the recognition scores (113) to identify those utterances with recognition scores (113) below the threshold as questionable utterances (111). At least one questionable utterance (111) is compared to other questionable utterances (111) from other calls and a group of similar questionable utterances (111) is formed. One or more of the similar questionable utterances (111) is selected from the group. A common manual transcription value (124) is received for the selected similar questionable utterances (111). The common manual transcription value (124) is assigned to the remaining similar questionable utterances (111) in the group.
    • 提供了一种使用混合语音转录有效降低转录错误的系统(10)和方法(40)。 语音流(22)被解析为话语。 初始转录值和相应的识别分数(113)分配给每个发音。 生成转录消息(23)并包括初始转录值。 对识别分数(113)应用阈值,以将具有低于阈值的识别分数(113)的那些话语识别为可疑话语(111)。 至少有一个有问题的话语(111)与来自其他呼叫的其他可疑话语(111)进行比较,并形成一组类似的可疑话语(111)。 从组中选择一个或多个相似的可疑话语(111)。 对于所选择的类似的可疑话语(111),接收到常见的手动转录值(124)。 共同手动转录值(124)被分配给组中剩余的类似的可疑话语(111)。
