C 2+N 1: The transition-metal-catalyzed reaction of alkenes with azides is an important tool for the formation of aziridines. Besides many recently published ruthenium, copper, and manganese catalysts, a novel macrocyclic tetracarbene iron(II) catalyst promotes the synthesis of aziridines in good yields and with low catalyst loadings.

New and improved methods and systems for modeling the performance of selected company metrics. Multiple, non-traditional sets of objective data along with mathematical analytical techniques are used to provide transparency and visibility into company performance relating to the particular metrics. Company inflection points and changes in strategy may be identified. The performance of a company and/or the performance of a selected industry or industry sector may be analyzed.

Systems and methods are provided for maintaining neutrality while trading a list of securities using an algorithmic trading facility coupled with at least one destination. This destination includes at least one alternative trading system (ATS). This facility is coupled, via an electronic data network, to a plurality of trading clients, and configured to receive a trade request to trade a list of securities from a trading client. This request includes user defined trading constraints that are used to generate and transmit trade orders to at least one ATS. The orders are transmitted based on trading data related to the destinations, the trade list, and the trading constraints. The facility can identify each executed trade corresponding to the trade orders and calculate a trade imbalance. The facility can determine whether the trade imbalance exceeds the trading constraints, and reallocate one or more of said submitted orders based on this determination.

A computer implemented method and system for executing block trades for a security includes steps or devices for receiving a block trade request, at a computer system. The block request includes data representing a quantity of shares of the security to be traded over a period of time. The computer system divides the period of time into a plurality of time bins. A computer system, for the received block trade request, computes, for each time bin, a number of shares to be traded as a trading target based on at least historical trading volumes using predictive analysis. For a first time bin, a computer system generates executable trade orders for a number of shares to be traded that is substantially equal to the trading target for the first time bin. A computer system executes at least a portion of the executable trade orders in a trade forum within each time bin in the future.

A trading platform computer system for detecting an abnormal trading condition of a security uses real-time and estimated values of one or more variables associated with the condition of the security to generate one or more analytic metrics that are compared to empirical distributions based on one or more peer groups for the security. An indicator can then be displayed to a trader as an indication of the abnormal condition.
